Polyaniline, Polyaniline/SiO2 and Poly(4-vinylpyridine): as Highly Efficient and Recyclable Green Heterogeneous Basic Catalysts for the Three-Component Synthesis of Tetrahydrobenzopyran and 3,4-Dihydropyrano[c]Chromene Derivatives
Polyaniline, polyaniline/SiO2, and poly(4-vinylpyridine) are highly effective base catalysts for the synthesis of tetrahydrobenzo[b]pyran and 3,4-dihydropyrano[c]chromene derivatives by the one-pot three-component condensation reaction of aryl aldehydes, malononitrile and α-hydroxy or α-amino activa...
