Formula: C4H10O2, Some examples of the diverse research done by chemistry experts include discovery of new medicines and vaccines, improving understanding of environmental issues, and development of new chemical products and materials. In a document type is Article, and a compound is mentioned, 19132-06-0, Name is (2S,3S)-Butane-2,3-diol, introducing its new discovery.

(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.

A series of glycosylated diol and triol derivatives was synthesized in order to serve as model compounds for the analysis of the stereochemistry, regiochemistry, and defect structures of poly(vinyl glycoside)s. 13C NMR spectroscopic analysis of these compounds revealed that the attached chiral carbohydrate substituents induced a strong correlation of the chemical shifts of both the anomeric C and the alpha-C atom of the aglycon with the absolute configuration of the latter. The influence of the stereoconfiguration of beta- and gamma-C atoms as well as the regiochemistry of the aglycon on the chemical shifts of the alpha-C and the anomeric C atom was also investigated.

Three commercial yeasts strains, namely, Saccharomyces cerevisiae SY, DV10, and Drop Acid Yeast, were used for Dangshan pear wine fermentation. Monitoring main physical and chemical indexes and scoring comprehensive sensory characteristics to find a suitable yeast to produce Dangshan pear wine. The fermentation cycle of SY was short (15 days), and the SY-fermented wine had a suitable sugar-acid ratio, with a residual sugar content of 3.13 ± 0.05 g/L, total acid content of 3.40 ± 0.11 g/L, and ethanol content of 14.1 ± 0.27% (v/v). Additionally, 42 flavor compounds were detected in fermented Dangshan pear wine, and the total amount of flavor compounds was highest in the SY wine (2,584.72 mug/L). Combined with the comprehensive sensory evaluation scores, these results suggest that Saccharomyces cerevisiae SY was the most suitable strain to produce Dangshan pear wine. Practical applications: In this study, we compared the physical and chemical indicators of pear wine brewed by different Saccharomyces cerevisiae in the process of fermentation and the final quality of pear wine products. It was concluded that the pear wine produced by Saccharomyces cerevisiae SY had good quality. The study found a strain suitable for the fermentation of pear wine and provided a theoretical basis for the industrial production of pear wine. Next, we can try to use Saccharomyces cerevisiae SY for large-scale production of pear wine and try to sell it on the market.
