Preparation of Optically Active α-Hydroxy Ketone Derivatives by Enzyme-Mediated Hydrolysis of Enol Esters

A new method of preparation of optically active α-hydroxy ketone derivatives has been developed.Incubation of (Z)-3-propionyloxy-4-benzyloxy-2-pentene (1a) with lipase OF gave optically pure (R)-enol propionate 1a, which in turn was converted without racemization to (R)-ketone 2a by the aid of LiAlH4.

SYNTHESIS OF (2S,3S)-2.3-OCTANEDIOL AND (S)-2-HYDROXY-3-OCTANONE, THE MALE SEX PHEROMONE OF THE GRAPE BORER XYLOTRECHUS PYRRHODERUS

(2S,3S)-2,3-Octanediol and (S)-2-hydroxy-3-octanone, the pheromone of the grape borer, were synthesized from (+/-)-1-octen-3-ol employing the Sharpless asymmetric epoxidation as the starting step.
