First example of multicomponent synthesis of 1-ethoxy-3-(4-aryl)-1-phenyl-1H-benzo[f]chromene derivatives

A new series of 1-ethoxy-3-(4-aryl)-1-phenyl-1H-benzo[f]chromenes have been synthesized efficiently. The procedure involves the multicomponent reaction of 2-naphthol, acetophenone derivatives, and triethyl orthobenzoate catalyzing by efficient bis(2-anilinotropone) Ti complex.
