Oxidative and reductive ring opening of endo-3,4-O-(4-methoxybenzylidene) acetals of 1,6-anhydro-β-D-galactopyranoses.

Cleavage of the endo-3,4-O-(4-methoxybenzylidene) acetal rings of 1,6-anhydro-β-D-galactopyranose derivatives with LiAlH4-AlCl3, NaCNBH3-HCl or NMe3-AlCl3 gives predominantly axial 3-O-(4-methoxybenzyl) ether derivatives.Oxidative opening of the same acetal functions with DDQ affords the corresponding 3-O-(4-methoxybenzoyl) derivatives.The (4-methoxybenzyl) group can be removed selectively with DDQ and survives acetolysis of the 1,6-anhydro bond.
