Synthesis of quinoxaline derivatives from substituted acetanilides through intramolecular quaternization reactions

De Castro, Sonia,Chicharro, Roberto,Aran, Vicente J.

, p. 790 - 802 (2007/10/03)

The cyclization of 2-dialkylamino-2′-halogeno- and 2-chloro-2′-(dialkylamino)acetanilides to quinoxaline derivatives has been studied in detail. These reactions proceed, respectively, through intramolecular aromatic nucleophilic or aliphatic nucleophilic
