A Simple Synthesis of Some New 2-Aryl-Substituted 2, 5-Dihydro-1H-1,5-benzodiazepine- and 2,5-Dihydro-1, 5-benzothiazepine-3,4-dicarboxylic N-Arylimides 2-Aryl-substituted 2,5-dihydro-1H-1,5-benzodiazepine- and 2, 5-dihydro-1,5-benzothiazepine-3,4-dicarboxylic N-aryl-imides are easily prepared in 25-94% yields by cyclocondensation of (Z/E)-1-aryl-4-arylmethylenepyrrolidine-2,3,5-triones with o-phenylenediamine or o-aminothiophenol in ethanol.
