Abstract

DERIVATIVES CONTAINING THE IMIDAZO [1, 2-A] PYRIDINE RING SYSTEM HAVE BEEN SHOWN TO POSSESS A BROAD RANGE OF USEFUL PHARMACOLOGICAL ACTIVITIES, INCLUDING ANTIBACTERIAL, ANTIFUNGAL, ANTHELMINTIC, ANTIVIRAL, ANTIPROTOZOAL, ANTI-INFLAMMATORY, ANTICONVULSANT, AND IMMUNOMODULATORY (KIFUNENSINE) ACTIVITIES [1-2].SEVERAL METHODS HAVE BEEN REPORTED FOR THE SYNTHESIS OF IMIDAZO [1, 2-A] PYRIDINE DERIVATIVES VIA A THREE-COMPONENT CONDENSATION OF 2-AMINOPYRIDIN WITH ALDEHYDES AND AN ISOCYANIDE [3-5].HOWEVER, IN MOST CASES THE YIELDS ARE GOOD AT HIGH TEMPERATURES AND SOME OF THE REAGENTS REQUIRE LONGER REACTION TIMES AND TEDIOUS PURIFICATION PROCEDURES. THUS, THERE IS A CERTAIN NEED FOR THE DEVELOPMENT OF AN ALTERNATIVE ROUTE FOR THE PRODUCTION OF IMIDAZO [1, 2-A] PYRIDINE, WHICH SURPASSESTHOSE LIMITATIONS.IN CONTINUATION OF OUR EFFORTS TO DEVELOP EFFICIENT AND ENVIRONMENTALLY BENIGN PROTOCOLS FOR THE SYNTHESIS OF HETEROCYCLES [6], WE REPORT HEREIN AN EFFICIENT SYNTHESIS OF THE IMIDAZO [1, 2-A] PYRIDINE DERIVATIVES BY THREE-COMPONENT CONDENSATION OF AN 2-AMINOPYRIDIN, AN ALDEHYDE, AND AN ISOCYANIDE IN THE PRESENCE OF CATALYTIC AMOUNTS OF CE (SO4) 2 AS AN INEXPENSIVEN CATALYST IN EXCELLENT YIELDS UNDER SOLVENT-FREE CONDITIONS.
