摘要：

The combination of electron-poor azomethine ylides 3 (AMY-I) or 4 (AMY-II) with electron-rich enamines 5 results in nonstereospecific 1,3-dipolar cycloadditions, which are LUMOdipole,-HOMOdipolarophile controlled reactions. This phenomenon can be explained only by a two-step mechanism via zwitterionic intermediates. (C) 1999 Elsevier Science Ltd. All rights reserved.
