SYNTHESIS OF SUBSTITUTED IMIDAZO[1,2-a]PYRIDIN-3-YL-ACETIC ACIDS BY MULTICOMPONENT CONDENSATION OF 2-AMINOPYRIDINES WITH ARYLGLYOXALS AND MELDRUM'S ACID

Abstract
A simple and effective method for the synthesis of substituted imidazo[1,2-a]pyridin-3-yl-acetic acids has been developed based on the multicomponent condensation of 2-aminopyridines with arylglyoxals and Meldrum's acid.
