Abstract
The present invention provides a method for producing an &agr;-acyloxy carbonyl compound from an enol ester epoxide stereoselectively using an acid catalyst which is capable of affecting rearrangement of the enol ester epoxide with inversion of stereochemistry. The present invention also provides a method for kinetic resolution of a stereoisomeric mixture of enol ester epoxides using a chiral catalyst. The kinetic resolution generally involves stereoselectively producing one particular enantiomer of &agr;-acyloxy carbonyl compounds from the stereoisomeric mixture of enol ester epoxides.
