Photooxygenation of 4-(5-methylfuran-2-yl)aminocyanopyridine derivatives

One pot syntheses of six-, seven-membered cycloalkane and pyrane junctured aminocyanopyridines bearing furan unit were successfully prepared from the ketones, 2-((5-methylfuran-2-yl)methylene) malononitrile, and ammonium acetate. Photooxygenation of 2-(4-aminocyanopyridine) substituted 5-methylfurans gave 1,4-dicarbonyl functionalized aminocyanopyridine derivatives in good yield in one single operation.
