Published information on heterocyclizations involving acetamidines and acetamidoximes substituted at the α-position with an electron-withdrawing group is reviewed, where these starting materials have been used in the synthesis of 2-aminoazaheterocycles (2-aminopyridines, 2-aminopyrroles, and 2‑aminoazirines). In such reactions the α-carbon atom of the amidine or amidoxime is included in the ring of the obtained heterocycle.
