FLUORESCENT N-HETEROCYCLES VIA ONE-POT TANDEM REACTIONS

Abstract

Substituted indolizines are very attractive heterocyclic units. On developing efficient methods toward differently substituted indolizines, we were particularly interested in elaborating efficient approaches toward three-component reaction of these compounds which are very interested from the point of view fluorescent properties. The microwave-mediated three component reaction of acyl bromide, bipyridine and dipolarophyl is catalyzed by basic alumina to give corresponding bis-indolizines in excellent yields in a one –pot reaction.
