of pentenyl and thiophenyl glycosides of N-acetylglucosamine (GlcNAc) as glycosyl donors for the direct preparation of O-glycosides of GlcNAc promoted by N-iodosuccinimide (NIS) and metal triflates in dichloromethane has been investigated. Both glycosyl acceptors 1-octanol and (-)-menthol resulted in good glycosylation yields for both types of donors with pentenyl glycosides being somewhat superior in
