Azabicyclic enaminones were obtained in good yields by flash vacuum pyrolysis of aminomethylene meldrum's acid derivatives. The reaction involves a -1,4 H shift from aminomethyleneketene intermediate followed by electrocyclisation of delocalized azomethine ylide.
通过快速真空热解氨基亚甲基me的酸衍生物,可得到高产率的氮杂双环烯酮。该反应涉及从氨基亚甲基烯酮中间体移出-1,4 H,然后将离域的偶氮甲亚胺叶立德电环化。
