Solid-Phase One Step Synthesis of 4H,4′-Exomethylene-bis[quinazolin-2-enols]

The solid-phase one step synthesis of 4H,4′-exomethylene-bis[quinazolin-2-enols] via 1,3-dipolar cycloaddition of urea on benzylideneacetophenone using Sb(III) chloride impregnated alumina is described. The reaction provides 80-85% dimeric quniazolinenols. The process is convenient, cost-effective a...
