The amide group in N-acetylglucosamine glycosyl acceptors affects glycosylation outcome

Glycosylation of a disaccharide containing N-acetylglucosamine with rhamnosyl and mannosyl trichloracetimidates under triethysilyl triflate catalysis led to the competitive formation of glycosyl imidates. While the rhamnosyl imidate could be rearranged to

Glycosylation of N-acetylglucosamine: Imidate formation and unexpected conformation

(Matrix presented) Rhamnosylation in mild conditions of a disaccharide containing N-acetylglucosamine afforded the imidate 6 while at higher temperature and concentration of promoter trisaccharide 7 was isolated. The kinetic imidate 6 was independently re
