Glycosidations of 2-deoxy glycosyl dithiophosphates using a tagged iodine(iii)-promoter for simple purification
Abstract
The preparation of the 4-i-butylsulfonate derivative of the Zefirov reagent (5) and its use in a novel purification strategy for iodine(III)-promoted glycosidations of 2-deoxy diethyldithiophosphate glycosides is described.
