Regioselectivity for intramolecular Diels-Alder (IMDA) reactions of 6-acetoxy-6-alkenylcyclohexa-2,4-dien-1-ones that were formed by oxidation of 2-alkenylphenols with lead tetraacetate in acetic acid were studied. Bridged regioselectivity was observed in the IMDA reactions of 6-acetoxy-6-alkenylcyclohexa-2,4-dien-1-ones having a dienophile part which could conjugate with an aromatic group. Bridged seven-and eight-membered rings and bicyclo[2.2.2]octane skeletons were constructed by the present IMDA reactions. Density functional theory (DFT) calculations suggested that conjugation of the dienophile with neighboring aromatic groups lowered the highest occupied molecular orbital-lowest unoccupied molecular orbital (HOMO-LUMO) energy gap and preceded bridged [4 + 2] adducts.

Disubstituted pendant-functionalized block copolymer consisting of insulating polynorbornene and conductive polyacetylene segments was synthesized by tandem metathesis polymerization, and displayed high dielectric constant of 30 and low dielectric loss of about 0.04, while behaved bad film-forming property, which could be improved by incorporating polycyclooctene into polynorbomene backbone. The generated flexible block copolymer with well-defined nanostructure exhibited a relatively high dielectric constant of 23, very low dielectric loss of below 0.0035, and high stored and released energy densities up to 4.52 and 4.02 J cm(-3) at the electric field of 165 MV m(-1),respectively, accompanied with the charge-discharge efficiency of 90%. The enhanced dielectric and energy storage capability were attributed to high permanent dipole moment and the interfacial polarization derived from the unique nanomorphology of block copolymer.

Demand for sustainable polar aprotic solvents is increasing due to their unique solubilizing properties and the toxicity of conventional analogs, which are facing pressure from extensive safety legislation. Polar aprotic solvents are particularly difficult to produce renewably because polar molecules that lack hydroxyl groups are rarely found in abundance in the natural world. Here, we explore the use of diformylxylose (DFX), a xylose-derived molecule that can be produced in a single step from lignocellulosic biomass, as a novel polar aprotic bio-based solvent. We notably demonstrate that diformylxylose shows a similar performance to conventional polar aprotic solvents (DMF, NMP, DMSO) in alkylation, cross-coupling (Heck), and hydrogenation reactions. We also demonstrate its straightforward production from commercial xylose and show that it is non-mutagenic, according to the Ames test. Renewable DFX appears to be a greener alternative to common polar aprotic solvents that are considered problematic for industry.

A versatile and DES-compatible bipyridine palladium complex has been developed as a general pre-catalyst for different cross-coupling reactions (Hiyama, Suzuki-Miyaura, Heck-Mizoroki and Sonogashira) in deep eutectic solvents. Hydrogen bond capacity of the ligand allows to keep the excellent level of results previously obtained in classical organic solvents. Palladium pre-catalyst showed a high catalytic activity for many cross-coupling reactions, demonstrating a great versatility and applicability. Also, this methodology employs sustainable solvents as a reaction medium and highlights the potential of DES as alternative solvents in organometallic catalysis. The catalyst and DES were easily and successfully recycled. The formation of PdNPs in DES has been confirmed by TEM and XPS analysis and their role as catalyst by mercury test. The dynamic coordination of bipyridine-type ligand in the palladium complex formation has been studied via UV/Vis.

The current study evaluated the key characters of aroma composition in diversified red wines (Cinsaut, Grenache, Cabernet Franc, Petit Verdot, Cabernet Sauvignon, Nielluccio, Tempranillo, Syrah, Merlot and Caladoc). Out of hundreds of volatile compounds 64 compounds were considered for study. Different groups consisting of fatty acids, volatile alcohols, aldehydes, esters, volatile phenols and terpenes were analysed using gas chromatography mass spectrometry coupled with thermal desorption (TD-GC-MS). Among all these diversified classes, alcohols were found as the most dominant group followed by esters and acids whereas aldehydes, phenols and terpenes were found to be minor compounds. Among the varieties, Nielluccio wine recorded highest concentration of total volatile compounds (191.53 mg/L) while, it was least in Caladoc wines (15.45 mg/L). The principal component analysis clearly differentiated Grenache wines based on their relationships between scores and their aroma composition followed by Nielluccio and Cinsuat wines. Out of sixty four compounds, only six aromatic compounds viz. butanediol, isoamyl actate, gamma-Terpene, butanol, acetic acid and furfural have satisfying aroma descriptors with floral and fruity nuances and contribute to differentiate the Grenache wines from other varieties which have similar scores in PC1 analysis. The cluster analysis also suggested that the wines in the same group (Cinsaut, Tempranillo and Syrah), (Cabernet Franc, Cabernet Sauvignon, Caladoc and Merlot) and (Nielluccio and Petit Verdot) had similar aroma characterization. Grenache wines were well differentiated from the sub group formed by other red varieties.

Methyl (E)-cinnamate is a specialized metabolite that occurs in a variety of land plants. In flowering plants, it is synthesized by cinnamic acid methyltransferase (CAMT) that belongs to the SABATH family. While rarely reported in bryophytes, methyl (E)-cinnamate is produced by some liverworts of the Conocephalum conicum complex, including C. salebrosum. In axenically grown thalli of C. salebrosum, methyl (E)-cinnamate was detected as the dominant compound. To characterize its biosynthesis, six full-length SABATH genes, which were designated CsSABATH1-6, were cloned from C. salebrosum. These six genes showed different levels of expression in the thalli of C. salebrosum. Next, CsSABATH1-6 were expressed in Escherichia coli to produce recombinant proteins, which were tested for methyltransferase activity with cinnamic acid and a few related compounds as substrates. Among the six SABATH proteins, CsSABATH6 exhibited the highest level of activity with cinnamic acid. It was renamed CsCAMT. The apparent Km value of CsCAMT using (E)-cinnamic acid as substrate was determined to be 50.5 mu M. In contrast, CsSABATH4 was demonstrated to function as salicylic acid methyltransferase and was renamed CsSAMT. Interestingly, the CsCAMT gene from a sabinene-dominant chemotype of C. salebrosum is identical to that of the methyl (E)-cinnamate-dominant chemotype. Structure models for CsCAMT, CsSAMT and one flowering plant CAMT (ObCCMT1) in complex with (E)-cinnamic acid and salicylic acid were built, which provided structural explanations to substrate specificity of these three enzymes. In phylogenetic analysis, CsCAMT and ObCCMT1 were in different clades, implying that methyl (E)-cinnamate biosynthesis in bryophytes and flowering plants originated through convergent evolution.

A new triazole-functionalized tetracarboxylic acid ligand (H4L) has been synthesized and utilized for the fabrication of a 3D Zn-II organic framework with a Zn-4(-COO)(6) cluster as the secondary building unit. The framework exhibits very good thermal stability and consists of dual functionalities of exposed Lewis acidic metal sites and accessible nitrogen-donor Lewis basic sites. The Lewis basic nitrogen sites in the framework serve as CO2 binding sites for highly selective CO2 capture and the presence of exposed Lewis acidic metal sites in the framework make it an efficient heterogeneous catalyst for the chemical fixation of CO2 into value-added cyclic carbonates under ambient conditions.

Application In Synthesis of 6H-Benzo[c]chromen-6-one. I found the field of Engineering very interesting. Saw the article Synergistic adsorption of Cu(II) and photocatalytic degradation of phenanthrene by a jaboticaba-like TiO2/titanate nanotube composite: An experimental and theoretical study published in 2019.0, Reprint Addresses Cai, ZQ (corresponding author), East China Univ Sci & Technol, Natl Engn Lab High Concentrat Refractory Organ Wa, Shanghai 200237, Peoples R China.; Liu, W (corresponding author), Peking Univ, Key Lab Water & Sediment Sci, Minist Educ, Coll Environm Sci & Engn, Beijing 100871, Peoples R China.. The CAS is 2005-10-9. Through research, I have a further understanding and discovery of 6H-Benzo[c]chromen-6-one.

Combined water pollution with the coexistence of heavy metals and organic contaminants is of great concern for practical wastewater treatment. In this study, a jaboticaba-like nanocomposite, titanate nanotubes supported TiO2 (TiO2/TiNTs), was synthesized by a two-step hydrothermal treatment. TiO2 /TiNTs had large surface area, abundant of -ONa/H groups and fine crystal anatase phase, thus exhibited both good adsorptive performance for Cu(II) and high photocatalytic activity for phenanthrene degradation. The maximum Cu(II) adsorption capacity on TiO2/TiNTs was 115.0 mg/g at pH 5 according to Langmuir isotherm model, and > 95% of phenanthrene was degraded within 4 h under UV light. TiO2/TiNTs showed about 10 times higher observed rate constant (k(obs) ) for phenanthrene degradation compared to the unmodified TiNTs. More importantly, the coexistence of Cu(II) promoted photocatalytic degradation of phenanthrene, because the incorporated Cu(II) in the lattice of TiNTs could trap photo-excited electron and thus inhibited the electron-hole recombination. Density functional theory (DFT) calculation indicated that the sites of phenanthrene with high Fukui index (f(0)) preferred to be attacked by center dot OH radicals. The quantitative structure-activity relationship (QSAR) analysis revealed that the degradation intermediates had lower acute toxicity and mutagenicity than phenanthrene. TiO2/TiNTs also owned high stability, as only slight loss of Cu(II) and phenanthrene removal efficiency was observed even after four reuse cycles. The developed material in this study is of great application potential for water or wastewater treatment with multi-contaminants, and this work can help us to better understand the mechanisms on reaction between Ti-based nanomaterials and different kinds of contaminants.
