A mild and efficient method for the synthesis of 3-methyl-1, 4-diphenyl-7, 8-dihydro-1 H-furo[3, 4-e]pyra-olo[3, 4-b]pyridin-5(4H)-one derivatives via one-pot, four-component reaction of aromatic aldehydes, tetronic acid, 3-aminobut-2-enenitrile, and Phenylhydrazine is described using Alum as catalyst. The features of this procedure are mild reaction conditions, excellent yields, short reaction time, and operational simplicity.
