The reaction between α-iminomethylene amino esters with different mono- and bidentate nucleophiles has been studied. It has been shown that the reactions with primary and secondary amines as monodentate nucleophiles afford 2-aminoimidazolones efficiently under very mild conditions. Judicious selection of the primary amines employed can modulate the regioselectivity. Analogous reactions employing bidentate
