Nucleophilic displacement by the cyanide anion of the 6-O-triflyl group in phenyl 6-O-triflyl-2,3-di-O-benzyl-4-O-p-methoxybenzyl-1-thio-β-D-galactopyranoside takes place via an intermediate 1,6-sulfonium salt resulting from the anchimeric assistance of the C-1 phenylthio group.

The highly stereoselective α(1 → 4) coupling between two D-galacturonic acid ester derivatives was accomplished in good yields, for the first time, using a phenylthioglycoside as donor. The method was designed to prepare D-galacturonic acid oligomers with methyl ester groups in definite positions.
