摘要
Such imidazolium methylides as imidazolium dicyanomethylide and bis(ethoxycarbonyl)methlide react with the methylenecyclopropenes with unsaturated substituents at the 4-position in the fashion of double cyclo-addition reaction, leading to the novel cage compounds, which involves an intermolecular 1,3-dipolar cyclo-addition reaction and an intramolecular Diels-Alder reaction.
