Abstract
Provided herein are methods for synthesizing cyclic carbonates, glycocarbonates, and polyglycocarbonates by reacting polyol glycans with carbon dioxide. Synthesis can include selective polycondensation of polyol glycan hydroxyl moieties.
Claims20
A method for making glycocarbonates, the method comprising reacting a polyol glycan with carbon dioxide, wherein the glycan comprises a closed chain structure and selected from one or more of the group consisting of hexose, a pyranose moiety, a pyranoside, and a furanose moiety, or a derivative thereof selected from the group consisting of α-Methyl 3 and 4 di-O-methyl 2 and 6 dihydroxyls glucopyranoside, α-Methyl 2 and 4 di-O-methyl 3 and 6 dihydroxyls glucopyranoside, D-α-methyl mannopyranoside, and D-α-methyl galactopyranoside.
