NOVEL PROCESS FOR THE PREPARATION OF CHIRAL COMPOUNDS DERIVED FROM HEXANOIC ACID ESTERS AND INTERMEDIATES USED IN THE SYNTHESIS OF CHIRAL2-(BROMOMETHYL)-2-ETHYLHEXANOIC ACID

摘要

The present invention comprises a novel process for the preparation of a chiral compound of formula (I) wherein R₁ is hydroxyl or a group which activates the carboxyl and R₂ is alkyl optionally substituted by halogen or benzyl, its preparation, its application in the synthesis of chiral 2-bromomethyl-2-ethylhexanoic acid and novel intermediates.
