title: Heteroannulation of nitroketene N,S-arylaminoacetals with POCl3: a novel highly regioselective synthesis of unsymmetrical 2,3-substituted quinoxalines.
abstract: [reaction: see text]. A novel regioselective route for the synthesis of substituted and fused 3-chloro-2-(methylthio)quinoxalines through POCl3-mediated heteroannulation of a range of alpha-nitroketene N,S-anilinoacetals has been reported.
