Synthesis, chemical property, and cytotoxicity of the carzinophilin congeners carrying a 2-(1-acylamino-1-alkoxycarbonyl)methylidene-1-azabicyclo[3.1.0]hexane system
摘要:
Synthesis of the title compounds was achieved by employing condensation of the 2-methoxy-1-pyrroline with ethyl nitroacetate and construction of 1-azabicyclo[3.1.0]hexane systems from 5-mesyloxymethylpyrrolidines as key steps. Some of these congeners which carry a C-6-C-11 unit involving the naphthalene part, were found to exhibit prominent cytotoxicity and effectively alkylate nucleophiles at both the aziridine and epoxide moieties.

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
