Iterative One‐Pot Synthesis of Oligosaccharides

Abstract

Straight to the point! Preactivation of a p-tolyl thioglycoside donor, followed by sequential addition of p-tolyl thioglycosyl acceptors in one reaction flask allowed rapid syntheses of oligosaccharides independent of anomeric reactivities of donors and acceptors (see scheme). This strategy greatly streamlines the assembly of oligosaccharides.
