Synthesis of the model compounds of carzinophilin carrying 2-methylidene-1-aza-bicyclo[3.1.0]hexane systems was achieved. Formation of malonylidenes or N-acyl-glycinylidenepyrrolidines was carried out by utilizing Eschenmoser's sulfide contraction or Herdeis's condensation between the 2-methylthio-Δ1-pyrrolone derivatives and ethyl nitroacetate, respectively. The 1-azabicyclo-[3.1.0]hexane systems
合成了带有2-亚甲基-1-氮杂-双环[3.1.0]己烷体系的卡那菲林模型化合物。malonylidenes或形成ñ酰基-glycinylidenepyrrolidines通过利用Eschenmoser的硫化物的收缩或Herdeis的2-甲硫-Δ之间的缩合进行1个分别-pyrrolone衍生物和硝基乙酸乙酯。1-氮杂双环-[3.1.0]己烷体系是通过碱促进的氮丙啶形成而构建的。
