The bicyclic 2,3,3a,4-tetrahydro-1H-imidazo[5,1-c][1,4]benzoxazin-1-one system and the related 1,4-benzo-thiazine and 4,1]benzoxazepine analogs were synthesized. They were easily obtained by melting a suitable diamine derivative with urea. Some of them displayed very good reversible MAO-I activity selective for type A. The preparation of the intermediate amines is also given.
