title: Microwave-assisted solvent-dependent reaction: chemoselective synthesis of quinoxalin-2(1H)-ones, benzo[d]imidazoles and dipeptides.
abstract: A microwave-assisted solvent-dependent chemoselective reaction dealing with 4-arylidene-2-phenyloxazol-5-ones and diverse ortho-diamines to achieve three types of molecular scaffolds, 3-benzylquinoxalin-2(1H)-ones, benzimidazole and β-amino dipeptides is reported. The procedures feature short reaction time, good to excellent yields, operational simplicity, as well as easily available starting materials. These compounds are of importance for organic chemistry and medicinal chemistry research.
