Efficient (3S)-acetoin and (2S, 3S)-2, 3-butanediol production from meso-2, 3-butanediol using whole-cell biocatalysis

(3S)-Acetoin and (2S, 3S)-2, 3-butanediol are important platform chemicals widely applied in the asymmetric synthesis of valuable chiral chemicals. However, their production by fermentative methods is difficult to perform. This study aimed to develop a whole-cell biocatalysis strategy for the production of (3S)-acetoin and (2S, 3S)-2, 3-butanediol from meso-2, 3-butanediol. First, E. coli co-expressing (2R, 3R)-2, 3-butanediol dehydrogenase, NADH oxidase and Vitreoscilla hemoglobin was developed for (3S)-acetoin production from meso-2, 3-butanediol. Maximum (3S)-acetoin concentration of 72.38 g/L with the stereoisomeric purity of 94.65% was achieved at 24 h under optimal conditions. Subsequently, we developed another biocatalyst co-expressing (2S, 3S)-2, 3-butanediol dehydrogenase and formate dehydrogenase for (2S, 3S)-2, 3-butanediol production from (3S)-acetoin. Synchronous catalysis together with two biocatalysts afforded 38.41 g/L of (2S, 3S)-butanediol with stereoisomeric purity of 98.03% from 40 g/L meso-2, 3-butanediol. These results exhibited the potential for (3S)-acetoin and (2S, 3S)-butanediol production from meso-2, 3-butanediol as a substrate via whole-cell biocatalysis.

Inverse agonists and antagonists of serotonin receptors are disclosed for use in treating sleep disorders such as insomnia, and specifically sleep maintenance insomnia. The compound increase slow wave sleep, decrease the number of awakenings after sleep onset, and decrease the time awake after sleep onset.

Novel and efficient one pot condensation reactions between ketones and aromatic alcohols in the presence of CrO3 producing alpha,beta-unsaturated carbonyl compounds

We report a new, effective and simple method for preparing alpha,beta-unsaturated carbonyl compounds by reacting ketones and aromatic alcohols at 56 C in the presence of CrO3 (CrO3 acts as an oxidant and also a catalyst) for around 10 h. The condensation reactions occurred effectively among a wide combination of ketones and alcohols. The procedure is simple and the yields can be high up to 98%. And a probable mechanism is proposed.

Highly regioselective primary etherification of racemic propane-1,2-diol by the tin(II) bromide-catalyzed reaction with diazo[bis(4-methoxyphenyl)]methane and the resolution of enantiomers with the help of Pseudomonas cepacia lipase

The tin(II) bromide-catalyzed reaction of diazo[bis(4-methoxyphenyl)]methane with racemic propane-1,2-diol in 1,2-dimethoxymethane resulted in the highly regioselective etherification of the primary hydroxyl group. After tritylation of the minor 2-ether, 1-[bis(4-methoxyphenyl)]methoxypropane-2-ol was obtained in pure form. The enantiomeric mono-ethers were resolved by kinetic resolution by transacetylation with the help of Pseudomonas cepacia lipase.

Synthesis of chiral beta3-aminoxy peptides

A series of chiral beta3-aminoxy acids or amides with various side chains have been synthesized via two different approaches. One is the Arndt-Eistert homologation approach, using chiral alpha-aminoxy acids as starting materials. The other approach, utilizing the enantioselective reduction of beta-keto esters catalyzed by baker’s yeast or chiral Ru(II) complexes, produces chiral beta3-aminoxy acids with nonproteinaceous side chains. The oligomers of beta3-aminoxy acids can be readily prepared using EDCI/HOAt as the coupling reagent.
