Sterically congested glycosyl-β-(1 → 4)-galactosides were stereoselectively obtained by the reduction of glycosidic spiroorthoesters in high yield. It was notable that mannosyl-β-(1 → 4)-galactosides were efficiently synthesized by this method, because β-selective mannosylation still remains a particular problem in oligosaccharide synthesis.
