概要

• 論文の詳細を見る

• The monoarylhydrazones(IIa—c) of benzocycloheptene-5,6-dione (I) underwent Fischer indolization to form 11,12-dihydrobenzo[5,6]cyclohept[1,2-<I>b</I>]indol-6-ones (IIIa—c). The treatment of IIIa—c with <I>N</I>-bromosuc-cinimide gave the benzoindolotropone derivatives (Va—c). Va, Vc, and VI afforded a dibromo compound (VII) on treatment with bromine in acetic acid.
