摘要

Abstract: Syntheses of 6-aryl-12H-indolo [2, 3-e][1, 4] benzodiazocine derivatives 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 ...
