Abstract:  Syntheses of 6-aryl-12H-indolo[2,3-e][1,4]benzodiazocine deriĀ­vatives 8 have been achieved for the first time by the reaction of 3-aroylmethylene-2H-indol-2-ones 4 with o-phenylenediamine 5 While the analogous reaction of 4 with ethylene diamine 9 resulted in exclusive formation of Schiff base derivatives viz. 1,3-dihydro-3-[2- (2-aminoethylimino)-2-aryl-ethylidene]indol-2-ones 12. The structures are assigned with the help of analytical and 1H, 13C NMR, DEPT, IR and mass spectral studies.
