摘要：

Chemospecific glycosidation of partially-benzoylated thioglycosides ("disarmed" acceptors) with perbenzylated thioglycosides ("armed" donors) can be realized in the presence of the promotor iodonium dicollidine perchlorate. The reaction results predominantly in the formation of α-linked saccharides and is compatible with the use of various protecting groups. © 1990.
