Enol acetates or ketones asymmetrically transformed to chiral acetates in h
igh yields with high optical purities through multistep reactions catalyzed
by a lipase and a ruthenium complex. 2,6-Dimethylheptan-4-ol was chosen as
a suitable hydrogen donor, and 4-chlorophenyl acetate was used as an acyl
donor for the conversion of ketones.
