Rhodium(II) catalyzed decomposition of vinyldiazomethanes containing either (R)-pantolactone or (S)-lactate as chiral auxiliary in the presence of N-(tert-butoxycarbonyl)pyrrole resulted in an enantioselective entry to tropanes by a tandem cyclopropanation/Cope rearrangement.
在N-(叔丁氧基羰基)吡咯存在下,铑(II)催化含有(R)-泛内酯或(S)-乳酸酯作为手性助剂的乙烯基重氮甲烷的分解,导致串联环丙烷化/对映体重排对映烷烃进入对映烷。
