Gram-scale syntheses of the (1-->3)-linked and (1-->4)-linked hyaluronan disaccharides

Carbohydr Res. 2004 May 17;339(7):1255-62. doi: 10.1016/j.carres.2004.03.005.

Abstract

The first gram-scale syntheses of two hyaluronan disaccharides are described. Construction of the (1-->4)-linked disaccharide 12 was achieved in 12% overall yield using 2,3-bis-dimethyl acetal protection in combination with chlorosilane-induced carbamate cleavage methodologies. The uronic acid functionality was installed using TEMPO oxidation with NaOCl as the hypochlorite source. The (1-->3)-linked disaccharide 18 was achieved in 7% overall yield utilizing acetonide protection in addition to the chlorosilane-induced carbamate cleavage methodology and the TEMPO oxidation.
