Single enantiomer (SS) and (RR) 2-[(phenoxy)(phenyl)methyl]morpholine derivatives 5, 8-23 are inhibitors of monoamine reuptake. Target compounds were prepared using an enantioselective synthesis employing a highly specific enzyme-catalysed resolution of racemic n-butyl 4-benzylmorpholine-2-carboxylate (26) as the key step. Structure-activity relationships established that serotonin and noradrenaline
单一对映异构体(SS)和(RR)2-[((苯氧基)(苯基)甲基]吗啉衍生物5、8-23是单胺再摄取的抑制剂。使用对映体选择性合成方法制备目标化合物,该方法采用高特异性酶催化的外消旋4-苄基吗啉-2-羧酸正丁酯(26)作为关键步骤。建立了构效关系,认为5-羟色胺和去甲肾上腺素的再摄取抑制是立体化学和芳基/芳氧基取代的功能。因此,所有选择性SRI,选择性NRI和双重SNRI均已确定。选择其中一种化合物,即强效和选择性双重SNRI(SS)-5a作为进一步临床前评估的候选药物。
