摘要
Reaction of O-acyl-protected glycosylthiols with dichloromethane afforded readily glycosylthiomethyl chlorides, which gave with sodium azide the corresponding glycosylthiomethyl azides 17-22. Reaction of these azides with dicyclopentadiene as dipolarophile led to tandem 1,3-dipolar cycloaddition/retro-Diels-Alder reaction furnishing the parent 1-glycosylthiomethyl-1,2,3-triazoles 23-25. Reaction of azides with acetylene derivatives gave directly 1-glycosylthiomethyl-1,2,3-triazoles which are ring-substituted.
