Pyridine Derivatives of Acridine and Quinoline

A convenient one-pot approach was proposed for the synthesis of new derivatives of 8,9,10,12tetrahydrobenzo[a]acridin-11(7H)-one and 10,12-dihydrobenzo[f]pyrimido[4,5-b]quinoline-9,11(7H,8H)-dione containing residues of nicotinic and isonicotinic acids covalently attached via ester groups in different positions of the aromatic core. Quaternary ammonium salts of the synthesized acridine derivatives as well as a metal complex with palladium PdLCl2 were obtained. These compounds contain a number of pharmacophore groups so going to be promising potential drugs with antimicrobial, antiviral, and antitumor activity.

100th Anniversary of Macromolecular Science Viewpoint: Degradable Polymers from Radical Ring-Opening Polymerization: Latest Advances, New Directions, and Ongoing Challenges

Radical ring-opening polymerization (rROP) allows facile incorporation of labile groups (e.g., ester) into the main chain of vinyl polymers to obtain (bio)degradable materials. rROP has focused a lot of attention especially since the advent of reversible deactivation radical polymerization (RDRP) techniques and is still incredibly moving forward, as attested by the numerous achievements in terms of monomer synthesis, macromolecular engineering, and potential biomedical applications of the resulting degradable polymers. In the present Viewpoint, we will cover the latest progress made in rROP in the last similar to 5 years, such as its recent directions, its remaining limitations, and the ongoing challenges. More specifically, this will be achieved through the three different classes of monomers that recently caught most of the attention: cyclic ketene acetals (CKA), thionolactones, and macrocyclic monomers.

How olive washing and storage affect fruit ethanol and virgin olive oil ethanol, ethyl esters and composition

BACKGROUND Olives are stored for a short time after harvesting pending processing in the oil mills. Furthermore, olives are often washed prior to fruit storage. In this work we study how washing and storage affect fruit ethanol content and the effect on virgin olive oil ethanol content and quality. RESULTS Olive storage produced an increase in the fruit ethanol content, achieving values six times higher when storage was in silos. Washing the olives resulted in an increase in fruit ethanol content, although when washed olives were processed immediately no difference was found. The increase in fruit ethanol content during storage was reflected in higher oil ethanol concentration. Similarly, olive washing resulted in oils with higher ethanol concentration. Industrial conditions gave more important increases in oil ethanol content than that from olives processed by hand. For quality parameters all the olive oils were classified as ‘extra virgin’. In general, oils showed a slight decrease in some sensory attributes. At industrial scale after 24 h storage oils were classified as ‘virgin’ because sensory defects were found. CONCLUSION Olive storage should be avoided or reduced to less than 12 h; if possible, olives should not be washed before storage since this practice favors losses in sensory characteristics and the synthesis of ethanol, a precursor of ethyl esters.

Switching from Biaryl Formation to Amidation with Convoluted Polymeric Nickel Catalysis

A stable, reusable, and insoluble poly(4-vinylpyridine) nickel catalyst (P4VP-NiCl2) was prepared through the molecular convolution of poly(4-vinylpyridine) (P4VP) and nickel chloride. We proposed a coordination structure of the Ni center in the precatalyst based on elemental analysis and Ni K-edge XANES, and we confirmed that it is consistent with Ni K-edge EXAFS. The Suzuki-Miyaura-type coupling of aryl halides and arylboronic esters proceeded using P4VP-NiCl2 (0.1 mol % Ni) to give the corresponding biaryl compounds in up to 94% yield. Surprisingly, when the same reaction of aryl halides and arylboronic acid/ester was carried out in the presence of amides, the amidation proceeded predominantly to give the corresponding arylamides in up to 99% yield. In contrast, the reaction of aryl halides and amides in the absence of arylboronic acid/ester did not proceed. P4VP-NiCl2 successfully catalyzed the lactamization for preparing phenanthridinone. P4VP-NiCl2 was reused five times without significant loss of catalytic activity. Pharmaceuticals, natural products, and biologically active compounds were synthesized efficiently using P4VP-NiCl2 catalysis. Nickel contamination in the prepared pharmaceutical compounds was not detected by ICP-MS analysis. The reaction was scaled to multigrams without any loss of chemical yield. Mechanistic studies for both Suzuki-Miyaura and amidation were performed.

Oligo(beta-peptoid)s with Backbone Chirality from Aspartic Acid Derivatives: Synthesis and Property Investigation

Poly(beta-peptoid)s (N-substituted poly-beta-alanines) are an intriguing class of pseudopeptidic materials for biomedical applications, but the polymers prepared by solution polymerization have restricted diversity and functionality due to synthetic difficulty. Synthesis of structurally diverse poly(beta-peptoid)s is highly desirable yet challenging. Herein, we report a new approach to synthesize skeletal chiral beta(3)-peptoid polymers from readily available aspartic acid derivatives. Two types of N-substituted beta(3)-homoalanine monomers, i.e., N-(methyl propionate)-Asp-OMe ((N) tBuP-Asp-OMe) and N-(tert-butyl propionate)-Asp-OMe ((N)tBuP-Asp-OMe), were synthesized in high yield via an aza-Michael addition reaction between Laspartic acid-l-methyl ester (L-Asp-OMe) and acrylate species. Both N-substituted beta(3)-homoalanines can be readily converted into polymerizable N-substituted beta(3) homoalanine N-carboxyanhydrides (beta-NNCAs). Subsequent ring-opening polymerization (ROP) of these beta-NNCA monomers provides access to oligo(beta-peptoid)s and mPEG-poly(beta-peptoid) diblocks with backbone chirality. Their conformations were preliminarily studied by circular dichroism (CD) spectra and Fourier transform infrared spectroscopy (FT-IR). The synthetic strategy would significantly facilitate the development of novel poly(beta-peptoid)s with well-defined and diverse structures.

Conversion of Sapropel on CoMo/Al2O3 Catalyst in Supercritical Ethanol

Sapropel hydroliquefaction in supercritical ethanol at 260 degrees C and a pressure of 18 MPa in the presence of CoMo/Al2O3 catalyst was studied. The maximal conversion of the sapropel organic matter (similar to 76%) in supercritical ethanol is reached when adding gaseous hydrogen and a catalyst. The process is accompanied by removal of nitrogen, oxygen, and sulfur and by an increase in the hydrogen content of the liquid products. As shown by gas chromatography-mass spectrometry and IR spectroscopy, the liquid products of sapropel conversion in supercritical ethanol consist mainly of esters (41.8-46.5%) and alkyl derivatives of phenol (18.6-21.6%).

A unique pathway to platform chemicals: aldaric acids as stable intermediates for the synthesis of furandicarboxylic acid esters

2,5-Furandicarboxylic acid (FDCA) has received attention as an emerging bio-based building block with many applications, especially in renewable polyesters. The common route to FDCA uses the unstable 5-hydroxymethylfurfural (HMF) as an intermediate. Here, we present an alternative route to FDCA and its esters using C6 aldaric acids as stable intermediates. Aldaric acids, or sugar diacids, can be obtained by the oxidation of C6 sugars or uronic acids from pectin. Subsequent dehydration of aldaric acids by solid acid catalysts in butanol produces furancarboxylates. Using silica-supported acid catalysts, over 90% yields of furancarboxylates were achieved with the selectivity to FDCA and its esters reaching 80%.

Effect of cooking temperature and time on total phenolic content, total flavonoid content and total in vitro antioxidant activity of garlic

Objective To investigate the effect of cooking temperature and time on the total phenolic content, total flavonoid content and antioxidant activity of aqueous and ethanolic extracts of garlic. Results The mean total phenolic content of fresh garlic were 303.07 +/- 6.58 mg gallic acid equivalent per 100 g (GAE/100 g) and 638.96 +/- 15.30 mg GAE/100 g of plant material for the aqueous and ethanolic extracts respectively. The mean total flavonoid content 109.78 +/- 6.78 mg quercetin equivalent per 100 g (QE/100 g) and 258.47 +/- 12.37 QE/100 g for aqueous and ethanolic extracts respectively. Fourier transform infrared spectral data showed absorptions in the range for carboxylic acids, hydroxyl group, esters, and alcohols, confirming the presence of phenols and flavonoids in the extracts. Cooking temperature had a significant effect on total phenolic content and total flavonoid content while cooking time did not have a significant effect on the phytochemicals and antioxidant activity.

Chromosome-level reference genome assembly provides insights into aroma biosynthesis in passion fruit (Passiflora edulis)

Passion fruit, native to tropical America, is an agriculturally, economically and ornamentally important fruit plant that is well known for its acid pulp, rich aroma and distinctive flavour. Here, we present a chromosome-level genome assembly of passion fruit by incorporating PacBio long HiFi reads and Hi-C technology. The assembled reference genome is 1.28 Gb size with a scaffold N50 of 126.4 Mb and 99.22% sequences anchored onto nine pseudochromosomes. This genome is highly repetitive, accounting for 86.61% of the assembled genome. A total of 39,309 protein-coding genes were predicted with 93.48% of those being functionally annotated in the public databases. Genome evolution analysis revealed a core eudicot-common gamma whole-genome triplication event and a more recent whole-genome duplication event, possibly contributing to the expansion of certain gene families. The 33 rapidly expanded gene families were significantly enriched in the pathways of isoflavone biosynthesis, galactose metabolism, diterpene biosynthesis and fatty acid metabolism, which might be responsible for the formation of featured flavours in the passion fruit. Transcriptome analysis revealed that genes related to ester and ethylene biosynthesis were significantly upregulated in the mature fruit and the expression levels of those genes were consistent with the accumulation of volatile lipid compounds. The passion fruit genome analysis improves our understanding of the genome evolution of this species and sheds new lights into the molecular mechanism of aroma biosynthesis in passion fruit.

Highly Stretchable, Self-Healable, and Adhesive Polyurethane Elastomers Based on Boronic Ester Bonds

Integrating stretchability, self-healability, and surface adhesive properties in a single material is attractive for expanding the applications in demanding fields. Herein, we have studied the metathesis kinetics of catechol-derived boronic esters and incorporated them into polyurethane (PU) networks to prepare a type of PU elastomeric vitrimers with excellent stretchability, healability, and adhesive properties. Two series of dynamic PU elastomers that have different cross-linking densities and varied fractions of catechol moieties were simply prepared by a solution casting method from the linear PUs containing pendent catechol groups and 1,4-phenylenediboronic acid. These elastomers possess excellent stretchability and moderate mechanical properties that can be readily manipulated by varying the crosslinking density and the number of residual catechol groups. Moreover, the elastomers are healable and reprocessable under mild conditions and show moderate adhesive capability. The effects of the cross-linking density and residual catechol fraction on the thermal relaxation profiles and adhesive strength of the elastomers were explored in detail. Finally, we have demonstrated the potential of this kind of dynamic PU elastomers for applications as stretchable, healable, and self-adhesive conducting composite materials.
