Regioselective De-O-benzylation with Lewis Acids

Simple and highly regioselective de-O-benzylations of poly-O-benzylated monosaccharides and polyols with Lewis acids (SnCl4 and TiCl4) were developed.Spectral studies on intermediates complexes showed that three appropriately situated metal chelating functional groups were necessary for the selective de-O-benzylation.

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.

Synthesis of the colitose determinant of Escherichia coli O111 and 3,6-di-O-(α-D-galactopyranosyl)-α-D-glucopyranoside

The synthesis of two branched trisaccharides, which constitute important elements of enterobacterial lipopolysaccharides are described.The common structural feature of each trisaccharide is α-D-glucopyranoside, upon which branching occurs at the O-3 and O

The mercury salt catalysed reaction of substituted α-D-galactosyl halides with the reactive 4-OH groups of the rhamnosides 18 and 19 were studied.The order of reactivity of the halides increases with the following substituents: O-acetyl O-glucosyl O-b
