Abstract A number of 1-thio-β-d-aldosides were prepared, directly or indirectly, from acetylated 1-halides of d-galactose, d-glucose, and 2-amino-2-deoxy-d-glucose. These aldosides have an amino group at the terminal position of the aglycon, in the form of 6- aminohexyl, 6-aminohexanoyl, or p-aminophenyl groups.
