Graphical Abstract

TOC: The first attempt to use glycosyl nitrates as glycosyl donors for O-glycosylation is presented. Lanthanide ions with higher charge-to-size ratios showed good affinity to bind the nitrate leaving group. High reaction yields were achieved with per-benzylated and per-benzoylated donors of the d-glucose and d-galactose series with both primary and secondary glycosyl acceptors in various solvents.

Abstract

Glycosyl nitrates are important synthetic intermediates in the synthesis of 2-amino sugars, 1,2-orthoesters or, more recently, 2-OH glucose. However, glycosyl nitrates have never been glycosidated. Presented herein is our first attempt to use glycosyl nitrates as glycosyl donors for O-glycosylation. Lanthanide triflates showed good affinity to activate the nitrate leaving group.
