We describe several synthetic routes to deoxyhydroxylaminosugar derivatives of the type Glyc-N (0H)-R where Glyc stands for a sugar moiety linked by any of its C-atoms except the anomeric one and R for one of the following substituants: H-atom, acyl, phosphoryl groups, aminoacid or sugar residues. Compounds of the above structure are potentially close analogs, homo-isosteres,-NOH-replacing-0-, of biochemically important molecules. Under ...
