Abstract

A green, efficient and simple procedure has been developed for the synthesis of Pyrano [2, 3-c] Pyrazoles from a one pot four component condensation of ethylacetoacetate, malononitrile, hydrazine hydrate and different substituted aromatic aldehydes using Tetrabutyl ammonium hydrogen sulphate (TBAHS) as green catalyst in
