The imidazo [2, 1-b] [1, 3]- and -[2, 4] benzodiazepin-2-one derivatives (4) and (13), and imidazo [1, 2-α] [1, 3] benzodiazepin-2-one derivative (9), of a potent blood platelet aggregation inhibitor, the imidazo [2, 1-b] quinazolin-2-one derivative (14), were synthesized as ring expansion analogs. Compound 9 showed potent activity but 4 and 13 showed poor activity and no activity, respectively.
