Optical resolution of acyclic α-hydroxy ketone derivatives by inclusion complexation
A new method for the preparation of optically active acyclic α-hydroxy ketone derivatives by thermodynamic resolution using a chiral host compound is described. We examined the resolution of racemic 2-benzyloxy-3-pentanone with chiral host compounds in va
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.
