ABSTRACT:
A process is provided for the preparation of a compound of formula (1)wherein R and R′ represent optionally substituted hydrocarbyl groups and X represents a hydrocarbyl linking group. The process comprises either the stereoselective reduction of the keto group in a dihydroxy keto precursor followed by selective esterification of a primary hydroxy, or selective esterification of a primary hydroxy of a dihydroxy keto precursor followed by stereoselective reduction of the keto group.
