NOVEL CHIRAL COMPOUNDS DERIVED FROM HEXANOIC ACID ESTERS, METHOD AND INTERMEDIATE CHEMICALS FOR THE PREPARATION AND USE THEREOF FOR SYNTHESIS OF 2-(BROMOMETHYL)2-ETHYL HEXANOIC CHIRAL ACID

摘要

The invention relates to a chiral compound of a formula (I), wherein R1 is hydroxyl or a carboxy activator group and R2 is alkyl eventually substituted by halogen or benzyl. The preparation and the use of the inventive compound for synthesis of 2-bromomethyl-2-ethyl hexanoic chiral acid and the novel intermediate chemicals are also disclosed.
