Synthesis of 2,3,8-trisubstituted 7H-isoindolo [5,6-g] quinoxaline-5,7,9,11(8H)-tetraones

摘要

Oxidation of 3-methyl-or 7,8-dimethylbenzo [g] quinoxalinedione produced the unusual product,dihydroxybenezo[g] quinoxaline-5,10-dione-carboxylic acid or dicarboxylic acid.This process was used for the synthesis of a series of 2,3,8-trisubstituted isoindolo[5,6-g] quinoxalinetetraone derivatives.
