Zhang, Haoqi published the artcileSynthesis of Novel Heterocycles by Amide Activation and Umpolung Cyclization, Related Products of catalysis-chemistry, the publication is Organic Letters (2020), 22(6), 2376-2380, database is CAplus and MEDLINE.
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 ¦Á-aryl amides and diverse alkylazides, effectively rerouting our previously reported ¦Á-amination transform.
