An alum [KAl (SO4)2.12H2O] catalyzed microwave assisted multicomponent synthesis of bioactive functionalized benzylpyrazolyl coumarin and quinolinone derivatives in PEG
Abstract
An efficient and environmentally benign method has been developed for the synthesis of benzylpyrazolyl coumarin and quinolinone derivatives, hydroxy coumarin derivatives using Alum [KAl (SO4)2.12H2O] catalyst and Polyethylene glycol as green solvent under microwave condition.
Keywords: Knoevenagel, Michael addition reaction, coumarins, quinolinones, alum, polyethylene glycol, multicomponent microwave irradiation method.
