Synthesis of Indolo[1,2-b]isoquinolinediones; Reduction of 2-[(Substituted Phenyl)methylidene]-3-oxo-2,3-dihydroindole
摘要:
Indolo[1,2-b]isoquinoline-5,12-dione and the isomeric 6,12-dione have been prepared respectively from 1-sulfonylindole and 1-acetyl-2-[(2-methoxycarbonyl phenyl)methylidene]-3-oxo-2,3-dihydroindole; the reduction of 1-acetyl-2-[(substituted phenyl)methylidene]-3-oxo-2,3-dihydroindole and their oxygen analogs with sodium borohydride have been studied.
