Abstract
A method for preparing a silicon glycan is provided. The method includes reacting (A) a polysaccharide and (B) an anhydride-functional organosilicon compound, to give the silicon glycan. The silicon glycan comprises a glycoside moiety, independently selected organosilicon moieties, and linking moieties joining the organosilicon moieties to the glycoside moiety. The glycoside moiety comprises independently selected saccharide moieties, which may be substituted with substituted or unsubstituted hydrocarbyl groups, ether moieties, and/or amine moieties.
Claims18
A method for preparing a silicon glycan, said method comprising:
- (1) reacting (A) a polysaccharide of formula
- where each A comprises an independently selected saccharide;
- each R is independently selected from substituted or unsubstituted hydrocarbyl groups, ether moieties, amine moieties, and H;
- each R1 is independently selected from substituted or unsubstituted hydrocarbyl groups and H;
- each Z1 is an independently selected ether moiety;
- each subscript o is independently 0 or 1;
- subscript x is from ≥0 to <1;
- subscript y is from 0 to 1, with the proviso that x+y=1;
- and moieties indicated by subscripts x and y may be in randomized or block form in the polysaccharide (A);
- and (B) an anhydride-functional organosilicon compound, to give the silicon glycan in the presence of a protic organic solvent.
