シリコングリカンおよびその調製方法
Document Type and Number:
Japanese Patent JP7463377
Kind Code:
B2
Abstract:
A silicon glycan is provided. The silicon glycan comprises a glycoside moiety, independently selected organosilicon moieties, and beta-amino alcohol moieties joining the organosilicon moieties to the glycoside moiety. The glycoside moiety comprises independently selected saccharide moieties, which may be substituted with hydrocarbyl groups, ether moieties, and/or amine moieties. A method of preparing the silicon glycan is also provided. The method includes reacting (A) an aminoethyl polysaccharide and (B) an epoxide-functional organosilicon compound, to give the silicon glycan. The method may include preparing the aminoethyl polysaccharide (A) by first reacting (At) a hydroxyl-functional polysaccharide and (A2) an aziridinium halide compound to give the aminoethyl polysaccharide (A).
