Abstract

Abstract The synthesis of 6, 9-difluoro substituted benzo [g] quinoxaline-5, 10-diones (3A), benzo [g] quinazoline-5, 10-diones (3B) and benzo [g] phthalazine-5, 10-diones (3C) have been accomplished. Treatment of 3A, 3B or 3C with diamines or N-(t-butoxycarbonyl) ethylenediamine led to the corresponding 6, 9-bis [(aminoalkyl) amino]-substituted analogues related to 2A, 2B and 2C, respectively. The mono-substituted derivatives 4h ...
