Efficient and Enantioselective Kinetic Resolution of Cyclic beta-Hydroxy Sulfides by Chiral 1,2-Diamine Catalyzed Asymmetric Acylation
Kinetic resolution of cyclic beta-hydroxy sulfides has been achieved by reaction with benzoyl chloride in the presence of a catalytic amount (0.1 mol%) of a chiral 1,2-diamine combined with triethylamine. This reaction affords the corresponding benzoates and unreacted alcohols with excellent enantioselectivities.
