Huang, Ya-wei et al. published their research in Shipin Gongye (Shanghai, China) in 2016 | CAS: 5444-75-7

2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Formula: C15H22O2

To study the flavor of japonica rice, sticky rice and aromatic rice in the 6 harvest rice of Wuchang zone, the anal. of the volatile components was used by solid-phase microextraction (SPME) and gas chromatog. coupled with mass spectrometry (GC-MS), comparing the difference between the different varieties. The results were drown out as follow: in the anal. of 6 cultivars, the aromatic rice Daohuaxiang 2 was observed to have the highest number of volatile compounds Tongnian 1 had the highest volatile compounds of the sticky rice. Chaochan 16 had the highest volatile compounds of the japonica rice. Except alkanes, cyclohexanol, 3,5-dimethyl-, undecanal, acrylic acid-2-Et ester, tetracosanol compounds and nonanal were only found in aromatic rice in cultivars. While Wuchang japonica rice contained the majority of straight-chain alkanes, only a few of the aldehyde acid esters of volatile compounds were detected. 2-Heptan-4-ol, n-caproic acid vinyl ester, trans-3-nonen-2-one and oxacycloheptadec-8-en-2-one (8z) were not found in other rice except for sticky rice, and these could be considered Wuchang sticky rice flavor compounds This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Formula: C15H22O2).

Zhang, Yu et al. published their research in Polymers for Advanced Technologies in 2021 | CAS: 102-09-0

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

With the aim to improve the compatibility of polycarbonate (PC)/polypropylene (PP) blends, a novel aromatic polycarbonate diol (PCDL) was synthesized by the transesterification reaction, then a series of polycarbonate-based thermoplastic polyurethane elastomers compatibilizers (TPU-Gx) with octadecyl side chains were successfully prepared by introducing different content of PCDL and glyceryl monostearate (2,3-Dihydroxypropyl octadecenoate; GMS). The structures of synthesized products were confirmed by Fourier transform IR spectroscopy and NMR hydrogen spectroscopy. Thermogravimetry results showed that all TPU-Gx had good thermal stability. The effects of TPU-Gx on the compatibilization of PC/PP blends were investigated in the aspect of morphol., mech., thermal, and rheol. properties. The results showed that all TPU-Gx could enhance the interfacial adhesion between PC/PP and improve the mech. properties of PC/PP blends. Among them, the addition of TPU-G1.5 containing 6.0 wt% PCDL and 1.5 wt% GMS made PC/PP/TPU-G1.5 blends show the highest impact strength, which increased by 54.1% when compared with that of pure PC/PP blends.

Herein is reported the first total synthesis of benzyl salicylate and benzyl gentisate glucosides present in various plant species, in particular the Salix genus, such as Populus balsamifera and P. trichocarpa. The method permits the synthesis of several natural phenolic acid derivatives and their glucosides starting from salicylic or gentisic acid. The divergent approach afforded access to three different acetylated glucosides from a common synthetic intermediate. The key step in the total synthesis of naturally occurring glycosides-the selective deacetylation of the sugar moiety-was achieved in the presence of a labile benzyl ester group by employing mild deacetylation conditions. The protocol permitted synthesis of trichocarpine (4 steps, 40% overall yield), isotrichocarpine (3 steps, 51% overall yield), trichoside (6 steps, 40% overall yield), and deoxytrichocarpine (3 steps, 42% overall yield) for the first time (>95% purity). Also, the optimized mild deacetylation conditions allowed synthesis of 2-O-acetylated derivatives of all four glycosides (5-17% overall yield, 90-95% purity), which are rare plant metabolites. This study involved multiple reactions and reactants, such as (2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3Formula: C16H22O11).

Mushroom, as a kind of higher fungus, is a precious homol. resource of medicine and foods. In this study, total lipids were extracted from eight wild edible mushrooms and subsequently characterized by ultra-high-performance liquid chromatog.-Quadrupole-Exactive Orbitrap mass spectrometry. 20 lipid classes and 173 mol. species were identified and quantified. Lipid mols. and their concentrations in Boletus speciosus, Boletus bainiugan, and Tricholoma matsutake exhibited significantly different behaviors compared with the remaining mushrooms. Hierarchical cluster anal. revealed that lipid profiles of B. bainiugan were most similar to B. speciosus followed by T. matsutake, Canthar-ellus cibarius, Sarcodon aspratu, Termitomyces eurrhizus, Laccaria laccata, and Thelephora ganbajun. In addition, several differential lipids can be considered as potential biomarkers to distinguish different mushroom species, for instance, lysophosphatidylethanolamine (16:1) and ceramide non-hydroxy fatty acid-dihydrosphingosine (d23:0-10:0). This study provided a new perspective to discriminate the mushroom species from the perspective of lipidomics.

Bisphenol A (BPA) is an endocrine disruptor compound, that is continuously released into the environment and is barely degraded in wastewater treatment plants. In this work, crude laccases from Pleurotus ostreatus and Pleurotus pulmonarius were used for the first time to degrade BPA in aqueous solution The residual BPA was quantified by HPLC and the BPA metabolites produced by action of the laccases were identified by GC-MS. BPA at 100 mg/L and 200 mg/L (0.88 mmol/L) were 100% and 85% removed, resp., in a 1 h reaction by both fungal laccases at a concentration of 8 U/L. Thirteen aromatic and aliphatic BPA metabolites were identified, including p-isopropenylphenol, methylpent-3-oic acid, ethyl-3-ethoxy propanoate, and 4-ethyl-2-methoxyphenol. The acute BPA toxicity decreased from 85% to less than 5% using the P. ostreatus laccase. P. pulmonarius laccase, did not caused reduction in toxicity, possibly because at least one BPA metabolite was as toxic as the parent compound itself. The results of this study suggest a feasible method for the complete removal of BPA from polluted environments using crude laccase from P. ostreatus.

The influence of polyphenol supplementation on ester formation during red wine alcoholic fermentation was written by Ling, Mengqi;Qi, Mengyao;Li, Siyu;Shi, Ying;Pan, Qiuhong;Cheng, Chifang;Yang, Weiming;Duan, Changqing. And the article was included in Food Chemistry in 2022.Computed Properties of C11H22O2 The following contents are mentioned in the article:

Pre-fermentative polyphenol supplementation in industrial scales (100-hL) and simulated fermentation (350 mL clarified juice) were conducted. The results showed that in practical winemaking, adding QCE (quercetin, caffeic acid and ellagic acid) increased acetate concentrations in wines and extra grape seed tannins (T) enhanced the effect of QCE supplementation. In simulated fermentation with clarified juice, the synergy effect of QCE and T was evidenced that ester formation was only promoted through mixed QCET supplementation. Besides, QCE supplementation benefited the formation of 4-vinylcatechol adducted malvidin-3-O-(acetyl/coumaroyl)-glucoside and decreased other anthocyanin derivatives derived from pyruvic acid and acetaldehyde, leading more pyruvic acid and acetaldehyde left in yeast to enhance the metabolic fluxes of esters. Findings manifested the connection between the formation of esters and anthocyanin derivatives during red wine alc. fermentation, which would be influenced by the phenolic matrix. This work could provide a perspective in winemaking industry for modulating aroma profile via polyphenol supplementation.

Haenniger, Sabine’s team published research in Scientific Reports in 10 | CAS: 16974-11-1

Scientific Reports published new progress about 16974-11-1. 16974-11-1 belongs to esters-buliding-blocks, auxiliary class Aliphatic Chain, name is (Z)-Dodec-9-en-1-yl acetate, and the molecular formula is C14H26O2, Recommanded Product: (Z)-Dodec-9-en-1-yl acetate.

Haenniger, Sabine published the artcileSexual communication of Spodoptera frugiperda from West Africa: Adaptation of an invasive species and implications for pest management, Recommanded Product: (Z)-Dodec-9-en-1-yl acetate, the publication is Scientific Reports (2020), 10(1), 2892, database is CAplus and MEDLINE.

Abstract: The pest species Spodoptera frugiperda, which is native to North and South America, has invaded Africa in 2016. The species consists of two strains, the corn-strain and rice-strain, which differ in their sexual communication. When we investigated populations from Benin and Nigeria, consisting of corn-strain and rice-corn-hybrid descendants, we found no strain-specific sexual communication differences. Both genotypes exhibited the same pheromone composition, consisting of around 97% (Z)-9-tetradecenyl acetate (Z9-14:Ac), 2% (Z)-7-dodecenyl acetate (Z7-12:Ac), and 1% (Z)-9-dodecenyl acetate (Z9-12:Ac), they had similar electrophysiol. responses, and all mated around three hours into scotophase. However, we found geog. variation between African and American populations. The sex pheromone of African corn-strain and hybrid descendant females was similar to American rice-strain females and showed higher percentages of the male-attracting minor component Z7-12:Ac. In addition, African males exhibited the highest antennal sensitivity towards Z7-12:Ac, while American males showed highest sensitivity towards the major pheromone component Z9-14:Ac. Increasing the production of and response to the critical minor component Z7-12:Ac may reduce communication interference with other African Spodoptera species that share the same major pheromone component. The implications of our results on pheromone-based pest management strategies are discussed.
