Abstract

Very recently, two significant contributions were made for the synthesis of cinnolines independently by Willis and Ge.[4] Willis et al. disclosed a two-step reaction sequence for the synthesis of cinnolines through the copper-catalyzed annulation of 2-(2-bromoalkenyl) aryl bromide with diethyl-1, 2-hydrazinedicarboxylate and subsequent aromatization (Scheme 2, route B).[4a] Ge et al. developed the copper-catalyzed intramolecular ...
