2-Acetamido-2,6-dideoxy-D-galactose

An analogous reaction of UDP-2-acetamido-2,6-dideoxy-D-xy/o-hexos-4-ulose (7d) results in formation of the derivatives of 2-acetamido-2,6-dideoxy-D-glucose and -D-galactose.166 These amino sugars were identified as components of several O-specific polysaccharides (for reviews, see Refs. 95 and 167). 

Springer and coworkers874 reported an extensive list of saccharides that were weakly inhibiting or noninhibiting. These included the 2-acetamido-2-deoxy derivatives of D-galactose, D-glucose, D-ribose, D-talose, and D-arabinose, 3,6-dideoxy-L- and -D-xy/o-hexose, L-lyxo-hexosulose, L-arabinose, D-fructose, and 2-deoxy-D-erythro-pentose.

TLC on silica gel G has been useful particularly in the organic synthesis of amino sugars for the characterization of derivatives which are not readily detected on paper. It has found application in the synthesis of 4-acetamido-4-deoxy-D- reofuranose [41], 2,6-diamino-2, 6-dideoxy-D-mannose dihydrochloride [42], 2,3-epimino-hexopyranosides [43], 2-amino-2,6-dideoxy-D-galactose [44], the l-O-acyl-2-acylamido-...
