Enzymatic Kinetic Resolution of 2-Cyclohexen-1-ol Derivatives
Optically active (S)-2-cyclohexen-1-ol derivatives and their enantiomeric (R)-acetates have been obtained in high enantiomeric excesses by enzymatic kinetic acetylation catalyzed by lipase AK.

A Novel Synthesis Including Asymmetric Synthesis of α,β-Unsaturated γ-Hydroxy Carbonyl Compounds from Enones with Carbon Homologation
Reaction of the carbanion derived from 1-chloroalkyl aryl sulfoxides with enones gave 1,2-adducts in good yields.Treatment of the adduct with potassium benzenethiolate afforded α-phenylthio β,γ-unsaturated carbonyl compound through an α,β-epoxy sulfoxide.
