Baeyer?Villiger monooxygenase-catalyzed desymmetrizations of cyclobutanones. Application to the synthesis of valuable spirolactones

A series of gamma-butyrolactone derivatives, including some spiranic ones, was obtained through desymmetrization of the corresponding prochiral 3-substituted cyclobutanones via Baeyer?Villiger monooxygenase (BVMO)-catalyzed oxidation. After reaction optimization using several commercial enzymes, both antipodes of various lactones were synthesized in most cases with >90% conversion and >80% enantiomeric excess under mild reaction conditions. In some cases alcohol formation was also observed (up to 40% conversion) as an undesired side reaction due to the presence of alcohol dehydrogenases in these preparations. Selected transformations were achieved on a 100 mg scale showing the possibilities of these oxidative biocatalysts as a new source of highly interesting compounds.

Direct bioconversion of d-xylose to 1,2,4-butanetriol in an engineered Escherichia coli

The compound 1,2,4-butanetriol (BT) is a valuable chemical used in the production of plasticizers, polymers, cationic lipids and other medical applications, and is conventionally produced via hydrogenation of malate. In this report, BT is biosynthesized by an engineered Escherichia coli from d-xylose. The pathway: d-xylose ? d-xylonate ? 2-keto-3-deoxy-d- xylonate ? 3,4-dihydroxybutanal ? BT, was constructed in E. coli by recruiting a xylose dehydrogenase and a keto acid decarboxylase from Caulobacter crescentus and Pseudomonas putida, respectively. Authentic BT was detected from cultures of the engineered strain. Further improvement on the strain was performed by blocking the native d-xylose and d-xylonate metabolic pathways which involves disruption of xylAB, yjhH and yagE genes in the host chromosome. The final construct produced 0.88 g L-1 BT from 10 g L-1 d-xylose with a molar yield of 12.82%. By far, this is the first report on the direct production of BT from d-xylose by a single microbial host. This may serve as a starting point for further metabolic engineering works to increase the titer of BT toward industrial scale viability.

Synthesis of eight glycosides of hexasaccharide fragments representing the terminus of the O-polysaccharide of Vibrio cholerae O:1, serotype Inaba and Ogawa, bearing aglycons suitable for linking to proteins

The title substances were prepared from intermediate, fully acetylated alpha-trimethylsilylethyl (SE) glycosides. The latter were assembled in a blockwise manner, using as the glycosyl donor the alpha-glycosyl chloride of a disaccharide bearing two 4-azido-4-deoxy functions. Next, the azido groups in the assembled hexasaccharides were converted to the corresponding amines, and these were acylated with 4-O-benzyl-3-deoxy-L-glycero-tetronic acid in the presence of a water-soluble carbodiimide. The SE glycosides were then transformed to glycosyl imidates, and these were coupled with methyl 6-hythoxyhexanoate or methyl 2-(2-hydroxyethylthio)propionate. The aglycons in the glycosides thus obtained were then converted to the corresponding carboxylic acids or acyl hydrazides. Such compounds are suitable for linking to proteins to obtain neoglycoproteins.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C4H4O3, you can also check out more blogs about4971-56-6

Stereoselective Hydrogen Transfer Reactions Involving Acyclic Radicals. Tandem Substituted Tetrahydrofuran Formation and Stereoselective Reduction: Synthesis of the C17-C22 Subunit of Ionomycin

The tandem iodoetherification reaction and stereoselective reduction of acyclic redicals has been used in the stereocontrolled synthesis of substituted tetrahydrofurans.Such a tetrahydrofuran intermediate is regioselectively cleaved using Me2BBr to reveal the acyclic array 2 which represents the C17-C22 subunit of ionomycin.In experiments that provide for a better understanding of hydrogen transfer reactions involving acyclic radicals, a significant improvement in the stereoselectivity is observed when the two substituents at the stereogenic center alpha to the radicalare imbedded in a cycle (“cycle effect”).A mechanistic rationale is discussed.
