Solvent-free one-pot rapid synthesis of 3-carboxycoumarins. using focused microwaves

Abstract

Reaction of 2-hydroxy- or 2-methoxy-substituted benzaldehydes or acetophenones with Meldrum’s acid in the presence of environmentally-friendly catalysts, like natural kaolinitic clays, EPZ10 and EPZG, without solvent using focused microwaves afforded 3-carboxycoumarins in excellent yields.
