ResumoAbstract Reactions of β‐(2‐furanyl)‐ and β‐(2‐thienyl)‐acrylonitrile with ethyl acetoacetate are reported. They lead to new polyfunctional derivatives of pyrano[2,3‐ b ]pyridine and pyrano[2,3‐ d ]‐pyrimidine. The structures of these products and the mechanisms of their formation are reported.
