Synthesis of Novel Heterocycles by Amide Activation and Umpolung Cyclization

[Image: see text] Herein, we report a metal-free synthesis of cyclic amidines, oxazines, and an oxazinone under mild conditions by electrophilic amide activation. This strategy features an unusual Umpolung cyclization mode and enables the smooth union of α-aryl amides and diverse alkylazides, effect...
