activated methylene reagents to afford high functionalised indolizines. However, in the absence of this tandem, the Knoevenagel condensation intermediate leads to bis-1,4-DHPs as a new class of nitrogen compounds.
2-甲酰基-1,4-DHP衍生物2与活化的亚甲基试剂一起串联Knoevenagel缩合/氨基腈环化,以提供高官能度的吲哚嗪。但是,在没有这种串联的情况下,Knoevenagel缩合中间体会导致bis-1,4-DHPs作为一类新的含氮化合物。
