Monoalkylation of amino acids of different structural types withN-chloroacetyl-glycosylamines was shown to be applicable for the preparation of glycoconjugates containing β-d-galactose,N-acetyl-β-d-glucosamine, β-d-mannose, and lactose residues. The glycoconjugates were synthesized from amino acids with secondary (sarcosine,l-proline) or primary (l-2- and 4-aminobutyric acids,l-tryptophan) amino groups
不同结构类型的氨基酸与 N-氯乙酰-糖胺的单烷基化被证明适用于制备含有 β-d-半乳糖、N-乙酰-β-d-葡糖胺、β-d-甘露糖和乳糖残基的糖缀合物。糖缀合物由具有二级(肌氨酸,l-脯氨酸)或一级(l-2-和4-氨基丁酸,l-色氨酸)氨基的氨基酸以及各种氨基二羧酸(N-甲基-dl-天冬氨酸、dl-天冬氨酸、l-谷氨酸和dl-2-氨基己二酸)。获得的衍生物可能对本系列生理活性化合物的糖靶向作用感兴趣。
