MODERN METHODS FOR THE SYNTHESIS OF INDOLO[2,3-b]QUINOXALINES

Abstract

In this minireview, we cover new methods for the synthesis of indolo[2,3-b]quinoxaline derivatives that have been published over the previous decade. The majority of the approaches reported in the literature rely on transition-metal-catalyzed cross-coupling reactions and direct С–Н functionalization, as well as intramolecular oxidative cyclodehydrogenation processes (SNH reactions).
