Poly(4-vinylpyridinium)hydrogen sulfate: An efficient and recyclable Bronsted acid catalyst for the synthesis of fused 3,4-dihydropyrimidin-2(1H)-ones and thiones

Fused ring 3,4-dihydropyrimidin-2(1H)-ones and thiones were synthesized by the one-pot three component condensation of 6-methoxy-1-tetralone, aromatic aldehydes and urea or thiourea under solvent-free conditions at 120 °C utilizing poly(4-vinylpyridinium)hydrogen sulfate as Bronsted acid catalyst.
