摘要：

The 1:1 zwitterionic intermediate generated from dimethyl acetylenedicarboxylate and isocyanide is intercepted with 2-hydroxy-1,4-naphthoquinone, 4-hydroxycoumarin, 4-hydroxy-1-methylquinolinone, 4-hydroxy-6-methylpyrone, and 1-naphthol in one-pot to give novel pyran annulated heterocyclic systems in good yields.
