9R)-benzomorphan stereochemistry. Only gamma-lactones 8, 9, 13, and 23, lacking the exocyclic methylene group, retain significant affinities for opioid receptor binding sites when compared with the reference compounds (2"S)-3 and (2"R)-3. As observed with these references compounds, greater binding affinity is also seen with gamma-lactone diastereomers having the 2"S stereochemistry in the nitrogen substituent
制备了在氮取代基中具有亲电基团的苯并吗啉,作为κ-阿片受体的潜在不可逆配体。这些是由去甲甲唑嗪与5-(碘甲基)-γ-丁内酯的对映异构体(11)的反应产物合成的。由具有“活性”(1R,5R,9R)-苯并吗啉立体化学的相应的饱和γ-内酯13和23制备α-亚甲基γ-内酯5和7以及环内α,β-不饱和γ-内酯8和9。当与参考化合物(2” S)-3和(2” R)-3相比时,仅缺少外环亚甲基的γ-内酯8、9、13和23保留对阿片样物质受体结合位点的显着亲和力。正如这些参考化合物所观察到的,
