Abstract:
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.
Abstract:
The invention relates to tetrapeptide derivatives of the general formula ##STR1## in which R represents a hydrogen atom, a straight-chain or branched alkyl radical containing from 1 to 5 carbon atoms, optionally substituted by a hydroxy, amino, mercapto, methylthio, methylsulphoxide, carboxy or guanidino group, or a benzyl or indol-3-ylmethyl radical optionally substituted by a hydroxy group,R.sub.1 represents a hydrogen atom or an alkyl group containing from 1 to 4 carbon atoms, ##STR2## represents a nitrogenous polycyclic structure, the enantiomers, epimers and diastereoisomers thereof, as well as to the pharmaceutically acceptable acid or base addition salts thereof.
Abstract:
There are now described some novel alpha-[1-aryl-2,2,2-trifluoroethoxy (or-ethylthio)]alkanoic acids that are useful for reducing triglycerides and cholesterol levels in the blood of animals. The percentage reduction in test rats has been observed to be from 20 to 65 for triglycerides and from 15 to 50 for cholesterol. A representative compound of the invention is alpha-(2,2,2-trifluoro-1-phenyl-1-ethoxy)butyric acid. Most of the compounds have an LD.sub.50 greater than 800 mg/kg, intraperitoneally, in male mice.A method of use, compositions, and a process for synthesis are also described.

Abstract:
Process for the industrial synthesis of (2S,3 7aS)-2-carboxyperhydroindole by reduction of 2-carboxindole or of one of its esters to (R,S)-2-carboxyindo or of one of its esters which, after saponification, converted into the acid, the S isomer cf (R,S)-2-carboxyindoline being obtained by precipitation from the mixture of the two (R) and (S) isomers, in the presence of (+) methylbenzylamine, (S)-2-carboxyindoline being in its turn subjected to catalytic hydrogenation to give (2S, 3aS,7aS)-2-carboxyperhydroindole, after separation of (2S,3aR,7aR) isomer by crystallization.Application to the synthesis of carboxyalkyl d peptides capable of being employed in therapeutics.
