Abstract

The quinoxaline nucleus is present in many pharmaceutical agents exhibiting a broad spectrum of biological activities such as antiviral, 1 antiglucoma, 2 and anticancer 3 activity. Recently, novel pyrrolo[1,2-a]quinoxalines have been proved to be potent and selective 5-HT 3 receptor ligands. 4 Because of this, a variety of conventional methods have been developed for the preparation of quinoxaline derivatives. 5 A solid-phase synthesis of quinoxalines has also been ...
