optimum was found to be exemplified by 2-(3,4-dichlorophenyl)-N-methyl-N-[(1S)-1-(1-methylethyl)-2- (1-pyrrolidinyl)ethyl]acetamide (13). Subsequently, racemic or chiral amino acids were used to introduce other alkyl and aryl substituents at C1 of the ethyl linking moiety. A series of potent compounds, bearing substituted-aryl groups at C1, were discovered, typified by 2-(3,4-dichloro-phenyl)-N-methyl-N-[(1R
本文描述了一系列N- [2-(1-吡咯烷基)乙基]乙酰胺及其相关类似物的合成,以及它们作为阿片样物质的生物学评价,这些酰胺在邻近酰胺氮(C1)的碳上被取代。激动剂。在研究的第一部分中,研究了当C1处的取代基为1-甲基乙基时,N-酰基,N-烷基和氨基官能团的变异体,并以2-(3,4-二氯苯基)为例进行了研究。 )-N-甲基-N-[(1S)-1-(1-甲基乙基)-2-(1-吡咯烷基)乙基]乙酰胺(13)。随后,使用外消旋或手性氨基酸在乙基连接部分的C1处引入其他烷基和芳基取代基。发现了一系列在C1上带有取代芳基的有效化合物,其典型值为2-(3,4-二氯-苯基)-N-甲基-N-[(1R,
