Carbasugar analogues of galactofuranosides: β-O-linked derivatives and towards β-S-linked derivatives

A selectively protected carbasugar analogue of β-galactofuranose was synthesised from glucose using ring-closing metathesis as the key step. The carbasugar was converted into an α-galacto configured 1,2-epoxide, which was an effective electrophile in Lewis acid catalysed coupling reactions with alcohols. The epoxide was opened with regioselective attack at C-1 to give β-galacto configured C-1 ethers. Using carbohydrates as nucleophiles, we synthesised a number of pseudodisaccharides. The epoxide was also regioselectively opened at C-1 with a sulfur nucleophile under basic conditions to give a β-galacto configured C-1 thioether.

Synthesis of carbadisaccharide mimics of galactofuranosides

A partially protected carbagalactofuranose was converted into a 1,2-anhydro derivative. This epoxide was opened with alcohol nucleophiles under Lewis acid catalysis to give β-carbagalactofuranose pseudodisaccharides with excellent regioselectivity.
