Abstract A convenient and rapid synthesis of 4‐(R)‐(naphthalen‐2‐yloxy)‐1‐(1‐phenyl‐(S)‐ethyl)‐pyrrolidin‐3‐(R)‐ol and 4‐(S)‐(naphthalen‐2‐yloxy)‐1‐(1‐phenyl‐(S)‐ethyl)‐pyrrolidin‐3‐(S)‐ol is disclosed. The reaction scheme is highlighted by the meso‐epoxidation of 1‐(1‐phenyl‐(S)‐ethyl)‐2,5‐dihydro‐1H‐pyrrole followed by addition of 2‐naphthol alkoxide to provide both expected diastereoisomers. Separation
摘要 4-(R)-(naphthalen-2-yloxy)-1-(1-phenyl-(S)-ethyl)-pyrrolidin-3-(R)-ol 和 4-(S)公开了-(naphthalen-2-yloxy)-1-(1-phenyl-(S)-ethyl)-pyrrolidin-3-(S)-ol。该反应方案的重点是 1-(1-苯基-(S)-乙基)-2,5-二氢-1H-吡咯的内消旋环氧化,然后加入 2-萘酚醇盐以提供两种预期的非对映异构体。通过结晶分离非对映异构体可以以适中的产率获得两种非对映异构体,而无需使用昂贵的手性催化剂。其中一种非对映异构体的 X 射线分析导致对每种非对映异构体的明确指定。这些手性吡咯烷类似物可用作天然产物、组合/平行合成和药物化学中的中间体。
