Regioselectivity in the reductive ring-opening reaction of 3,4,6-tri-O-benzyl-1,2-O-benzylidene and 3,4,6-tri-O-benzyl-1,2-O-p-methoxybenzylidene-alpha-D-glucopyranose using diisobutyl aluminum hydride (DIBAH) was examined. The ratio of the 1-O- and 2-O-p-methoxybenzyl ethers, which were generated from endo-type 1,2-O-p-methoxybenzylidene, was variable by the change of solvent.
