Abstract
Treatment of ‘-anhydro-4-(5-0-acety1-2-0-triflyl-fl-D-xylofuranosyl)uracil β-D-xylofuranosyluracil with LiCl in hexamethylphosphoric triamide afforded the 2’-“up” chloride of the anhydronucleoside, i.e. 2’-triflate group was directly displaced by the chloride nucleophile. All attempts to hydrolyze the 2,3’-anhydro linkage resulted in the formation of 2’-chloro-2’,3’-didehydro-dideoxynucleoside.
