  Efficient Assembly of 1-(1H-Imidazol-1-yl)-3-methylene-1H-indenes via Tandem Reaction of (2-(Alkynyl)benzylidene)malonates with Imidazoles

  摘要：

  The tandem nucleophilic addition and 5-exo-cycliyition of (2-(alkynyl)benzylidene)malonates with imidazole derivatives in the presence of t-BuOK is reported. This reaction proceeds smoothly under mild conditions with high selectivity to afford the corresponding 1-(1H-imidazol-1-yl)3-methylene-1H-indene-2,2(3H)-dicarboxylates in good to excellent yields.
