Stereoselective synthesis of α-linked saccharides by use of per O-benzylated 2-pyridyl 1-thio hexopyranosides as glycosyl donors and methyl iodide as an activator

Article abstract of DOI:10.1016/S0040-4020(01)86571-6

A new, practical, stereoselective glycosidation methodology is described where per O-benzylated 2-pyridyl 1-thio-α/β-hexopyranosyl donors of D-gluco-(1), D-galacto- (2), D-manno- (3) and L-rhamno- (4) configurations have been efficiently coupled with dive
