摘要:
Process for the industrial synthesis of perindopril, in which (2S,3aS,7aS)-2-carboxyperhydroindole is condensed with N-[(S)-1-carbethoxybutyl]-(S)-alanine after protection of the carboxyl group, the product resulting from the condensation being then subjected to deprotection of the carboxyl carried by the heterocyclic ring.The (2S,3aS,7aS)-2-carboxyperhydroindole and N-[(S)-1-carbethoxybutyl]-(S)-alanine are themselves obtained in excellent conditions from 2-carboxyindole and from L-alanine respectively, both available on an industrial scale.
