An efficient method for targeting a variety of symmetrical and asymmetrical alpha-substituted dithiomalonates (DTMs) is described, utilizing 1H-imidazole-1-carbothioates as reactive acylating agents and MgBr2 center dot OEt2/DBU or LiHMDS for soft or hard enolization conditions of thioesters, respectively. The utility of this methodology was demonstrated through the synthesis of the pyridopyrimidine mesoionic insecticides: triflumezopyrim and dicloromezotiaz.

The majority of cytochrome P450 enzymes (CYPs) predominantly operate as monooxygenases, but recently a class of P450 enzymes was discovered, that can act as peroxygenases (CYP152). These enzymes convert fatty acids through oxidative decarboxylation, yielding terminal alkenes, and through alpha- and beta-hydroxylation to yield hydroxy-fatty acids. Bioderived olefins may serve as biofuels, and hence understanding the mechanism and substrate scope of this class of enzymes is important. In this work, we report on the substrate scope and catalytic promiscuity of CYP OleT(JE) and two of its orthologues from the CYP152 family, utilizing alpha-monosubstituted branched carboxylic acids. We identify alpha,beta-desaturation as an unexpected dominant pathway for CYP OleT(JE) with 2-methylbutyric acid. To rationalize product distributions arising from alpha/beta-hydroxylation, oxidative decarboxylation, and desaturation depending on the substrate’s structure and binding pattern, a computational study was performed based on an active site complex of CYP OleT(JE) containing the heme cofactor in the substrate binding pocket and 2-methylbutyric acid as substrate. It is shown that substrate positioning determines the accessibility of the oxidizing species (Compound I) to the substrate and hence the regio- and chemoselectivity of the reaction. Furthermore, the results show that, for 2-methylbutyric acid, alpha,beta-desaturation is favorable because of a rate-determining alpha-hydrogen atom abstraction, which cannot proceed to decarboxylation. Moreover, substrate hydroxylation is energetically impeded due to the tight shape and size of the substrate binding pocket.

A dual experimental/theoretical investigation of the Ireland-Claisen rearrangement of tetrasubstituted alpha-phthalimido ester enolates to afford alpha-tetrasubstituted, beta-trisubstituted alpha-amino acids (generally >20:1 dr) is described. For trans allylic olefins, the Z- and E-enol ethers proceed through chair and boat transition states, respectively. For cis allylic olefins, the trend is reversed. As a result, the diastereochemical outcome of the reaction is preserved regardless of the geometry of the enolate or the accompanying allylic olefin. We term this unique convergence of all possible olefin isomers global diastereoconvergence. This reaction manifold circumvents limitations in present-day technologies for the stereoselective enolization of alpha,alpha-disubstituted allyl esters. Density functional theory paired with state-of-the-art local coupled-cluster theory (DLPNO-CCSD(T)) was employed for the accurate determination of quantum mechanical energies.

Ethnopharmacological relevance: Danggui Buxue Tang (DBT) has been used to promote hematopoiesis and relieve myelosuppression in China. Antibiotics can cause myelosuppression through gut microbiota disorders. Aim of the study: This study aims to explore the way of DBT to alleviate the metabolic disorder caused by antibiotics. Materials and methods: In this study, 16S rRNA sequencing was used to detect the change of gut microbiota, metabolomics to analyze the change of metabolites. Correlation analysis was used to establishment the correlation between gut microbiota and metabolites. PICRUST 2 was used to predict the function of gut microbiota. Results: Results showed that eighty-two genera of gut microbiota were affected by antibiotic, while twelve were significantly restored after DBT. Seventy-four potential metabolites were significantly different from the antibiotics and DBT. We found significant recovery by the Bacteroides and Rikenellaceae RC9 after DBT. The metabolic pathways influenced by the antibiotic treatment included primary and secondary bile biosynthesis, etc. The metabolic pathways that could be restored after DBT included the primary and secondary bile acid biosynthesis pathway, etc. Through correlation analysis, we found a correlation between the Bacteroides, Rikenellaceae_RC9_gut_groupand other potential differential metabolisms such as those of taurodeoxycholic acid, N-phenylacetyl glycine, etc. The functional prediction showed that the biosynthesis of primary bile acid, secondary bile acid was significantly affected. Conclusions: DBT can restore the gut and reverse the metabolic disorder caused by antibiotics through Bacteroides, and it provides a new medical idea regarding the gut microbiota balance.
