and 7 were similar to morphine in analgesic potency in rats and mice and showed physiological effects that were identical with those of morphine and that were completely reversed by naloxone. Compound 7 was identical with morphine in its ability to displace [3H]naloxone from homogenates of rat brain minus cerebellum. A molecular mechanics analysis of the m-methoxyphenyl analogue 6a showed that the nitrogen
通过将1-芳基-4、4-二甲氧基-1,2-环丁烷二酰亚胺5进行氢化还原,合成了一系列5-芳基-3-氮杂双环[3.2.0]庚烷-6-缩酮6。 1,1-二甲氧基乙烯与2芳基马来酰亚胺的[2 + 2]光环加成反应的唯一的区域选择性产物。用EtSNa -DMF将间甲氧基苯基-N-甲基类似物6a脱甲基为苯酚7。6a和7在大鼠和小鼠的镇痛效力上均与吗啡相似,并显示出与吗啡相同的生理作用,并被纳洛酮完全逆转。化合物7与吗啡的相同之处在于它能从大鼠脑减去小脑的匀浆中置换[3H]纳洛酮。对间甲氧基苯基类似物6a的分子力学分析表明,氮原子,甲氧基苯基
