Process for the preparation of dihydroxy esters and derivatives thereof |
摘要 |
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. |
