Synthesis of benz[f] indole-4,9-dione derivatives via intramolecular cyclization (II)

Abstract

The new N-aryl-benz[f]-indole-4,9-dione derivatives were synthesized via intramolecular cyclization when triethylamine was employed as a base for the reaction of 2-chloro-3-(α-cyano-α-ethoxycarbonyl-methyl)-1,4-naphthoquinone and arylamines.
