Owing to the steric hindrance of the adjacent sialyl moiety, the introduction of two sialic acid units to the compact and rigid 3,4 di branched galactoside unit is very challenging and the β-selective and efficient glycosylation of the galactosamine moiety at the 4-position of di branched galactose is also problematic.
WebSialic acids comprise a varied group of nine-carbon amino sugars that are widely distributed among mammals and higher metazoans. ... Their general structure is characterized by a biphenyl moiety joined through an amide bridge with an acidic hydroxyazole scaffold (hydroxylated thiadiazole, pyrazole and triazole).
