Catalytic transformation of esters of 1,2-azido alcohols into α-amido ketones

Kim, Yongjin,Pak, Han Kyu,Rhee, Young Ho,Park, Jaiwook

supporting information, p. 6549 - 6552 (2016/06/01)

The esters of 1,2-azido alcohols were transformed into α-amido ketones without external oxidants through the Ru-catalyzed formation of N-H imines with the liberation of N2 followed by intramolecular migration of the acyl moiety. A wide range of α-amido ketones were obtained, and one-pot transformation into the corresponding oxazoles (or a thiazole) was demonstrated.
