Direct intramolecular double cross-dehydrogentive-coupling (CDC) cyclization of N -(2-pyridyl)amidines under metal-free conditions

A facile transition-metal-free protocol to form 2-iminoimidazo[1, 2- ]-pyridines bearing a -CHBr group and an aza-quaternary carbon center at the 3 position from -(2-pyridyl)amidines substrates, in which the new heterocyclic skeletons constructed from amidines radical reactions or nucleophilic subst...
