Synthesis of new furopyrans and angularly fused furopyranochromenes from 3-arylmethylidenefuran-2-ones

Reactions of 5-aryl-3-arylmethylidenefuran-2-ones with malononitrile gave 6-amino-2,4-diaryl-4Hfuro[2,3-b]pyran-5-carbonitriles and 2-aryl-5-imino-5H, 11bH-furo[3′,2′: 5,6]pyrano[3,4-c]chromen-6-amines as potentially biologically active substances.

Synthesis of 6-amino-4-aryl- 2R-4H-furo[2,3-b]pyran-5-carbo- nitriles based on the condensation of 3-arylmethylene-3H-furan-2-ones with malononitrile

Methods were developed for the synthesis of 6-amino-4-aryl-2R-4H-furo[2,3- b]pyran-5-carbonitriles based on the reaction of 3-arylmethylene-3H-furan-2-ones with malononitrile and also using a multicomponent reaction. The reaction schemes are discussed.
