Abstract
Abstract The present investigation deals with a novel water soluble Lewis acid complex, Zn [(L) proline] 2 catalyzed Hantzsch 1, 4-dihydropyridine derivatives syntheses in aqueous medium assisted by microwave irradiation. The microwave promoted syntheses in aqueous medium afforded moderate to excellent yield (up to 98%) within short reaction time and allowed the reaction to take place with low microwave power (200 W). This synthetic ...
