Attempts to synthesise alpha-C-glycosides of N-acetylgalactosamine by selective deprotection at C-2' of allyl alpha-C-galactoside 1 and subsequent amination failed, but opened the way to alpha-C-talopyranosides. The synthesis of alpha-C-glycosides of N-acetylgalactosamine was performed from allyl alpha-C-glucopyranoside 9, which was regioselectively deprotected, stereoselectively aminated at C-2', and finally epimerised at C-4'.
