Imino Derivatives of Amino-alditols

Cyclic imino derivatives of amino-alditols.- Several laboratories have reported studies on these compounds, which can show glycosid-ase inhibitory activity. Fleet s group has studied the plant alkaloids (22)-(24) which are analogues of glucose, fructose, and mannose respectively analysis of the inhibitory activity of these compounds towards a variety of glycosidases has shown that the 

Full details of the synthesis of 4-amino-l,5-dideoxy-l,5-iminohex-itols reported earlier (Vol.16,p.94) have been published. 

Acetonation of D-mannitol with methyl isopropenyl ether in DMF at room temperature with acid catalysis gave principally the 1,2 5,6-di-0-isopropylidene diacetal with small amounts of the 1,2 4,6- and 1,2 3,4-isomers 

4-0-(2-Acetamido-2-deoxy-D-glucopyranosyl)-D-ribitol derivatives have been prepared from D-ribitol as artificial antigens for an immunogenicity study mono-allylation of 2,3,5-tri-O-benzyl-D-
