Article abstract of DOI:10.1246/bcsj.56.2849

Partial benzylation of methyl α-D-galactopyranoside with benzyl chloride and LiOH selectively gave the 2,3,6-tribenzyl ether, while that using KOH or RbOH gave the 2,4,6-isomer as the main product.Methyl β-D-galactopyranoside afforded the 3,4,6-tribenzyl ether predominantly, irrespective of the alkali used.
