The disaccharides related to glycosyl phosphatidyl inositol anchors of membrane proteins, 4-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-D-myo-inositol-1-phosphate and 4-O-(2-amino-2-deoxy-α-D-galactopyranosyl)-D-chiro-inositol-1-phosphate, have been prepared from optically resolved myo-inositol derivatives.The chiro-inositol moiety was obtained by epimerization of a selectively blocked myo-inositol-triflate ester.The resolved inositols were subsequently phosphorylated to yield the disaccharide aglycones.The amino-sugar components were prepared by azidonitration of suitably protected glucal and galactal derivatives.The derived pyranosyl chlorides were then condensed with the inositol phosphates using silver triflate as the promoter.
