Silver(D-Catalyzed Dual Activation of Propargylic Alcohol and Aziridine/Azetidine: Triggering Ring-Opening and Endo-Selective Ring-Closing in a Cascade

摘要

[Ag(COD)2]PF6 catalyzes the reaction between propargylalcohols and N-tosylaziridines/azetidines leading to a di-verse range of N,0-heterocycles, namely, oxazines, oxaze-pines, and oxazocines via ring-opening and ring-closing ina cascade
