The present invention describes a novel method for the synthesis of (2S,3aS,7aS)-octahydroindole-2-carboxylic acid, or of one of its aryl esters of formula XIII
wherein X and Y are a hydrogen atom, a halogen, alkyl, alkoxyl or nitro group, and the conversion of the paranitrobenzyl ester of formula X
into Perindopril of formula I
or one of its salts.
本发明描述了一种新的方法,用于合成
(2S,3aS,7aS)-八氢吲哚-2-羧酸或其式XIII的芳基酯之一,其中X和Y是氢原子、卤素、烷基、烷氧基或硝基基团,并将式X的对硝基苄酯转化为公益普利或其盐之一的式I。
