Glycosyl trifluoroacetimidates. Part 1: Preparation and application as new glycosyl donors

Glycosyl (N-phenyl)trifluoroacetimidates, readily prepared from 1-hydroxyl sugars by treatment with (N-phenyl)trifluoroacetimidoyl chloride in the presence of K2CO3, were demonstrated to be effective glycosyl donors.
