title: Concise chemical synthesis of a tetrasaccharide repeating unit of the O-antigen of Hafnia alvei 10457.
abstract: Concise chemical synthesis of a tetrasaccharide repeating unit of the O-antigen of Hafnia alvei 10457 is reported. Construction of the tetrasaccharide as its 4-methoxyphenyl glycoside was achieved by condensation of less abundant monosaccharide units such as, D-galactofuranose, N-acetyl-D-galactosamine and N-acetylneuraminic acid. The synthetic strategy consists of the preparation of suitably protected required monosaccharide intermediates from the commercially available reducing sugars and high yielding glycosylation reactions.
