The idea of using biaryl structures to generate synthetic building blocks such as spirolactones is attractive because biaryl structures are abundant in biomass waste streams. However, the inertness of aromatic rings of biaryls makes it challenging to transform them into functionalized structures. In this work, we developed photoinduced dearomatization of nonphenolic biaryl compounds to generate spirolactones. We demonstrate that dearomatization can be performed via either aerobic photocatalysis or anaerobic photooxidation to tolerate specific synthetic conditions. In both pathways, dearomatization is induced by electrophilic attack of the carboxyl radical. The resulting spirodiene radical is captured by either oxygen or water in aerobic and anaerobic systems, respectively, to generate the spirodienone. These methods represent novel routes to synthesize spirolactones from the biaryl motif.

Herbs market is constantly growing worldwide, and is trying to find new species and varieties coming from specific geographical regions. While the increasing production demands novel solutions for product preservation, consumers demand guaranteed quality for these products. In case of herbs, the most common preservation method is thermo-based process – drying, which strongly affects products quality. Regarding the technological possibilities and efficiency, convective drying (CD), microwave drying, vacuum-microwave drying (VMD) and combined convective pre-drying followed by vacuum-microwave finish-drying (CPD-VMFD) methods are the most popular ones. In this study, the influence of the drying methods (CD, VMD and CPD-VMD) on Thai basil (O. basilicum var. thyrsiflora) quality was evaluated for the very first time. The chemical composition of their essential oils (EOs), dried samples (aroma profiles, APs) and sensory quality of the dried products were also studied. As a result of multiple chemical and sensory analyses and after cross-checking all these results, guidelines for chemical markers of Thai basil aroma quality were established. Odour-active compounds (OACs) contribution in Thai basil EOs did not show a clear pattern to link it with quality assessments; however, OACs contribution in APs did. The drying treatments leading to the dried products with the highest quality were: (i) 2 h CPD at 50 degrees C followed by VMFD with 360 W (2 h CPD50) and (ii) 1 h CPD at 70 degrees C followed by VMFD with 360 W (1 h CPD70).

Alpinia galanga is a wild medicinal plant having tremendous industrial importance. However, lack of quality planting material in natural resources restricted its wide exposure in industrial sector. Thus, a standardised protocol for stable supply of quality planting materials with genetical and phytochemical stability is need of the hour to meet commercial requirements. The current study reports an efficient protocol to regenerate micropropagated plantlets with long term stability in molecular as well as phytochemical level. Murashige and Skoog (MS) media augmented with 3 mg/l 6-Benzyladenine (BA), 3 mg/l Kinetin (Kn) and 1 mg/l Napthalene Acetic acid (NAA) was found optimum for regeneration and multiplication of plantlets. In order to establish genetic stability molecular marker-based profiling of micropropagated plants were done at every 6 months intervals up to 6 years. Monomorphic banding pattern were found that are identical to the mother plants. After six years of in vitro conservation, the regenerated plants were transplanted to the field and its drug yielding potential were evaluated through phytoconstituent analysis along with bioactivity studies. A comparative Gas chromatography (GC) and mass spectroscopy (MS) analysis of essential oils showed no significant differences in phytoconstituents between the conventional and in vitro propagated plants. The bioactivities like antioxidant, antimicrobial and anticancerous study along with total phenolic and total flavonoid content of in vitro plants were compared with mother plants and found stable with negligible variation. Thus, the present study has enough significance towards commercial exploitation of A. galanga with phytochemical and molecular stability.

Current pharmacological therapies for the management of chronic articular diseases are far from being satisfactory, so new strategies need to be investigated. We tested the intra-articular pain relieving properties of a system of molecules from a characterizedCentella asiaticaextract (14G1862) in a rat model of osteoarthritis induced by monoiodoacetate (MIA). 14G1862 (0.2-2 mg mL(-1)) was intra-articularly (i.a.) injected 7 days after MIA, behavioural and histological evaluations were performed 14, 30 and 60 days after treatments. Moreover, the effect of 14G1862 on nitrate production and iNOS expression in RAW 264.7 macrophages stimulated with LPS was assessed. In vitro, 14G1862 treatment attenuated LPS-induced NO production and iNOS expression in a comparable manner to celecoxib. In vivo, 14G1862 significantly reduced mechanical allodynia and hyperalgesia, spontaneous pain and motor alterations starting on day 14 up to day 60. The efficacy was higher or comparable to that evoked by triamcinolone acetonide (100 mu g i.a.) used as reference drug. Histological evaluation highlighted the improvement of several morphological parameters in MIA + 14G1862-treated animals with particularly benefic effects on joint space and fibrin deposition. In conclusion, i.a. treatment withCentella asiaticais a candidate to be a novel effective approach for osteoarthritis therapy.

A series of palladium(H) complexes incorporating l-substituted-3-methyl-3-phospholenes as the P-ligands were prepared from phospholene oxides by deoxygenation followed by complexation with PdCl2(PhCN)(2). The two 1-substituted-3-methyl-3-phospholene ligands were trans position to each other in the Pd(II)-complexes. As the ligands contain a P-stereogenic center, the Pd-complexes were obtained as a 1:1 mixture of two stereoisomers, the homochiral (R,R and S,S) and the meso (R,S) forms, when racemic starting materials were used. An optically active Pd-complex containing (R)-1-propyl-3-phospholene ligand was also prepared. Catalytic activity of an aryl- and an alkyl-3-phospholene-palladium(II)-complex was evaluated in hydroalkoxycarbonylation of styrene. The alkyl-derivative showed higher activity and selectivity towards the formation of the esters of 3-phenylpropionic acid. However, the overall activity of these PdCl2(phospholene)(2)-type complexes was low.

A targeted synthesis of dodecasubstituted type I porphyrins that utilizes the reaction of unsymmetrical 3,4-difunctionalized pyrroles and sterically demanding aldehydes was developed. This way, type I porphyrins could be obtained as the only type isomers, likely due to a minimization of the steric strain arising from peri-interactions. Uniquely, this method does not depend on lengthy precursor syntheses, the separation of isomers, or impractical limitations of the scale. In addition, single-crystal X-ray analysis was used to elucidate the structural features of the macrocycles.

Radical hydroboration reactions have only recently been reported and are still rare. Here we describe a photoredox radical hydroboration of alpha,beta-unsaturated esters, amides, ketones, and nitriles with NHC-boranes that uses only an organocatalyst and visible light. The conditions are mild, the substrate scope is broad, and the alpha/beta regioselectivity is high. The reaction requires only the organocatalyst; there is no costly metal, and there are no other additives (base, cocatalyst, initiator).

A stable and reproducible layer of Prussian blue (PB) modified with copper was electrodeposited on carbon paper electrodes for the multiple detection of ester flavorants with a bienzymatic biosensor. Carbon fiber composite paper was investigated as high-surface, low-cost substrate for biosensor development. The pre-activation of the electrode surface by cyclic voltammetry was necessary to improve the electrochemical properties before the electrochemical deposition of Prussian blue-copper film (PB-Cu). The stability and the reproducibility of the obtained PB-Cu carbon paper electrode was demonstrated at pH 7.4, optimum for biosensor development. The developed biosensor is based on the immobilization of two enzymes (carboxyl esterase and alcohol oxidase) by cross-linking with glutaraldehyde onto PB-Cu carbon paper electrode. A mixture of key aroma ester compounds (methyl butyrate, ethyl butyrate, methyl cinnamate and ethyl cinnamate) was detected in several food samples with low interferences.
