20,22-环氧甾醇在BF_(3)·Et_(2)O作用下重排反应的研究

The Rearrangement of a 20,22-Oxidosteroid Catalyzed by BF_(3)·Et_(2)O

本文研究了20,22-环氧甾醇3a在BF_(3)·Et_(2)O作用下的重排反应.鉴定了所得十种产物(1a,1b,10,11,12或13,14,15,16,17和18的结构,并讨论了这些产物的生成机理.

The rearrangement of the 20,22-epoxide,3a,catalyzed by BF_(3)·Et_(2)O was investigated.The structures of ten products obtained in this reaction(1a,1b,10,11,1 or 13,14,15,16,17 and 18)were determined and the mechanism discussed.
