Deoxy sugars trideoxyhexoses

Uridine 5 -(2-acetamido-2-deoxy-a-n-gIucopyranosyluronic acid pyrophosphate) (36) was isolated from extracts of Achromobacter georgiopolitanum14Sa and Micrococcus lysodeikticus.149b The ester of uridine 5 -pyrophosphate with an unusual amino sugar, namely, a 2-acetamido-2,4,6-trideoxyhexose of unknown configuration, has... 

Several rare amino sugars have been found in antibiotics. From puro-mycin (Achromycin), 3-amino-3-deoxy-D-ribose has been isolated by Waller and co-workers 260). The configuration of the amino sugar was confirmed by its synthesis from L-arabinose, with methyl 2,3-anhydro-i -L-ribopy-ranoside 261) as an intermediate (p. 392). Among the hydrolysis products of erythromycin, obtained from Streptomyces erythreus, is an amino sugar with the empirical formula CsHnNOs. Its structure has been partially determined as a 3-dimethylamino-3,4,6-trideoxyhexose 262). On hydrolysis...
