<i>p</i>-TSA catalyzed tandem conjugate addition/annulation/elimination process for the synthesis of 2,4-disubstituted-4<i>H</i>-benzo[<i>f</i>]chromenes

983-988A simple and user friendly protocol for the synthesis of biologically important 2,4-diaryl-4H-benzo[f]chromenes has been described starting from the readily available naphthols and chalcones catalyzed by p-TSA
