propargyl and n-pentenylglycosides has been identified. According to this methodology, n-pentenylglycosides can be selectively activated with NIS/TMSOTf in the presence of either armed or disarmed propargyl O-glycosides. In addition, we report herein that propargyl 1,2-orthoesters can be selectively activated with AuBr3 in CH2Cl2 at room temperature in the presence of n-pentenylglycosides. Similarly
