Synthesis of polyhydroxy [n]-polyurethanes derived from a carbohydrate precursor

Polyhydroxy [n]-polyurethanes with chains formed by sugar-derived units have been synthesized. The enantiomerically pure monomeric precursor 1-amino-1-deoxy-2,3:4,5-di-O-isopropylidene-Dgalactitol (4) was prepared from D-galactono-1,4-lactone (1) by a three-step route. Acetonation of 1 with 2,2-dime...
