Some oxo-linked 5a-carba-di- and tri-saccharides of biological interests including 5a-carbamaltose, were synthesized by coupling of 5a-carba-glycosyl donor, 1,2-anhydro-5a-carba-β-d-mannopyranose derivative with the alkoxides generated from the protected hexopyranose derivatives in N,N-dimethylformamide in the presence of a crown ether.
