A microwave-assisted solvent-dependentchemoselective 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
