The synthetic process equivalent to C-unsubstituted (CH) nitrile ylides cycloaddition reaction is achieved via cycloaddition of NH-azomethine ylide and the following fission reaction of the cycloadducts under acidic conditions. Cycloaddition of NH-azometh

N-Unsubstituted pyrrolidine derivatives are prepared by the cycloaddition of an N-unsubstituted azomethine ylide in the pyrido[1,2-a]pyrimidin-4(4H)-one system and olefinic dipolarophiles. The acid treatment of the cycloadducts, pyrrolidines, caused a fis
