Synthetic alpha- and beta-(2----4)- and alpha- and beta-(2----8)-linked disaccharides of 3-deoxy-D-manno-octulopyranosonic acid (Kdo), of which the synthesis of the beta-(2----4)-linked compound is described here, were used to develop a simple GLC-MS method for the determination of their anomeric co
Treatment of methyl 2,4,5,7,8-penta-O-acetyl-3-deoxy-cr-D-manno-oct-2ulopyranosonic acid, or its methyl ester, with refluxing methanolic O.lM hydrogen chloride for 16 h gave 95% of methyl (methyl 3-deoxy-a-D-manno-act-2-ulopyranosid)onate. Acetylation of the methyl ester of 3-deoxy-D-manno-act-2ulo
