The disaccharides related to glycosyl phosphatidyl Inosltol anchors of membrane proteins, 4--(2-amino-2-deoxy-α--glucopyranosyl)---inositol-1-phosphate and 4--(2amino-2-deoxy-α-D-galactopyranosyl)---inositol-1-phosphate, have been prepared from optically resolved -inosltol derivatives. The -inositol moiety was obtained by epimerlzatlon of a selectively blocked -inositol-trifiate ester. The resolved
与膜蛋白的糖基磷脂酰肌醇锚定物有关的二糖4- (2-氨基-2-脱氧-α--吡喃葡萄糖基)-肌醇-1-磷酸酯和4- (2氨基-2-脱氧-α- D-半乳糖吡喃糖基)-肌醇-1-磷酸酯是由光学拆分的-肌醇衍生物制备的。的是由选择性堵塞的epimerlzatlon获得肌醇部分肌醇-三氟甲磺酸酯的酯。随后将分解的肌醇磷酸化以产生二糖苷元。氨基糖组分是通过叠氮腺酮适当保护的葡糖和半乳糖衍生物制备的。然后使用三氟甲磺酸银作为促进剂,将衍生的吡喃糖基氯与肌醇磷酸酯缩合。
