The N-phenethyl analogues of (1R*,4aR*,9aS*)-2-phenethyl-1,3,4,9a-tetrahydro-2H-1,4a-propanobenzofuro[2,3-c]py ridin-6-ol and 8-ol and (1R*,4aR*,9aR*)-2-phenethyl-1,3,4,9a-tetrahydro-2H-1,4a-propanobenzofuro[2.3-c]py ridin-6-ol and 8-ol, the ortho- (43) and para-hydroxy e- (20), and f-oxide-bridged 5-phenylmorphans (53 and 26) were prepared in racemic and enantiomerically pure forms from a common precursor
(1R*,4aR*,9aS*)-2-phenethyl-1,3,4,9a-tetrahydro-2H-1,4a-propanobenzofuro[2,3-c]pyridin-6-的N-苯乙基类似物ol 和 8-ol 和 (1R*,4aR*,9aR*)-2-phenethyl-1,3,4,9a-tetrahydro-2H-1,4a-propanobenzofuro[2.3-c]pyridin-6-ol 和8-ol、邻-(43) 和对-羟基 e-(20) 以及 f-氧化物桥连的 5-苯基吗喃 (53 和 26) 是从常见的前体季盐制备的外消旋和对映异构纯形式12. 光学拆分通过与合适的对映体纯手性酸形成盐或通过手性载体上的制备型 HPLC 来完成。在小鼠试验中发现 N-苯乙基 (-)-对-e 对映异构体 (1S,4aS,9aR-(-)-20) 是一种 μ-阿片激动剂,具有类似吗啡的镇痛活性。相比之下,N-苯乙基
