Abstract The synthesis of O -glycosylated N 1 -( p -hydroxycinnamoyl)spermidines was investigated. p -Hydroxycinnamate glycosides of some amino sugars, including a synthetic intermediate of a unique antibiotic, cinodine, were prepared and converted into the amide of spermidine.

Abstract A keysyntheticintermediate for the diaminohexosyloxycinnamate moiety of glycocinnamoylspermidines was synthesized from d -galactose by two routes, via 3,4,6-tri-O-acetyl-2-azido-2-deoxy- d -galactopyranosyl nitrate (20) and via 1,6-anhydro-2-azido-2-deoxy-β- d -galactopyranose (12), in 16 and 22 steps, respectively.
