Abstract

A simple and convenient method has been developed for the regioselective synthesis of new 3,4,5-trisubstituted pyrazole derivatives via 1,3-dipolar cycloaddition of diazo ketone to 2,3-dienoates obtained from the condensation products of dicarboxylic acid anhydrides and 3-aminobutanoic aicd.
