procedure for the synthesis of pyrido[2,1-c][1,4] benzodiazepine-6,12-dione ( 1 ) and 1,4-benzodiazepine-2,5-diones ( 2a – 2d ), using microwave irradiation and/or conventional heating is reported. The configuration of 1 was determined by single-crystal X-ray diffraction. A detailed ab initio B3LYP/6-31G* calculation of structural parameters and substituent effects on ringinversionbarriers (Δ G # ) and
