Extractive biocatalysis: A powerful tool in selectivity control in yeast biotransformations

The effect of absorbing resins on the yeast reduction of α,β- unsaturated carbonyl compounds is reported. Enantioselectivity, chemoselectivity and space-time yields of the biotransformation are impressively enhanced. The distribution of substrates and products between the resin and the water phase shows that the improved selectivity has to be attributed to the control of substrate concentration.

SYNTHESIS OF 1-SUBSTITUTED (S)-4-ACETOXY-1-PENTEN-3-ONES USING (S)-LACTIC ACID AS A CHIRAL SOURCE AND THEIR SYNTHETIC REACTIONS

Ylide reaction of (S)-3-acetoxy-1-triphenylphosphoranylidene-2-butanone, derived from (S)-lactic acid, with aldehydes gives 1-substituted (S)-4-acetoxy-1-penten-3-one derivatives, which are shown to be transformed into useful chiral compouds by stereosele
