Glucopyranosyl chloride Koenigs-Knorr reaction with

The 1,2-cw-glycosides are prepared by a modification of the Koenigs-Knorr reaction. Reaction of the peracetylated carbohydrate with phosphorous pen-tachloride in carbon tetrachloride gives 3,4,6-tri-( -acetyl-2-0-trichloroacetyl-3-D-glucopyranosyl chloride [77] (reaction 4.57), which reacts with alkyl and aryl nucleophiles to form the a-glycopyranoside (reaction 4.62).
