NOUVEAUX COMPOSES CHIRAUX DERIVES D'ESTERS DE L'ACIDE HEXANOIQUE, PROCEDE ET INTERMEDIAIRES DE PREPARATION, UTILISATION A LA SYNTHESE DE L'ACIDE 2-(BROMOMETHYL) 2-ETHYL HEXANOIQUE CHIRAL
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.
