Abstract

Good yields of substituted coumarins were obtained by a synthetic method involving the Pechmann reaction using vanadium(III)chloride (VCl3) reagent to effect this condensation under solvent-free conditions. ... Keywords: coumarins, vanadium(III) chloride, Pechmann reaction. ... Coumarins and chromones are naturally occurring important plant constituents and occupy a unique place in natural and synthetic organic chemistry. Plants belonging to the natural ...
