Validation of the 2‐fluoro substituent as an inert steering group to control chemicalglycosylation is presented. A molecularediting study has revealed that the exceptional levels of diastereocontrol in glycosylation processes by using 2‐fluoro‐3,4,6‐tri‐O‐benzyl glucopyranosyl trichloroacetimidate (TCA) scaffolds are a consequence of the 2R,3S,4S stereotriad. This study has also revealed that epimerization

Syntheses of various (2-deoxy-2-fluoro-glycosyl)amino-acids are described. This new class of acid stable glycoconjugates was accessible by electrophilic fluorination of glycals, followed by coupling with suitable protected serine and aspartic acid derivates.
