Synthesis and characterization of poly-O-methyl-[n]-polyurethane from a d-glucamine-based monomer

Aminoalditol 1-amino-1-deoxy-d-sorbitol (1) was readily converted into 2,3,4,5-tetra-O-methyl derivative 5, a key precursor of a sugar-based [n]-polyurethane. For the polymerization, the free amino or primary hydroxyl groups of 5 were selectively activated and employed as starting monomers in two al...
