Silver(I)-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 propargyl alcohols and N-tosylaziridines/azetidines leading to a diverse range of N,O-heterocycles, namely, oxazines, oxazepines, and oxazocines via ring-opening and ring-closing in a cascade
