A general way for the functionalization of ribonucleosides is described. The method involves the synthesis of the methyl-ribofuranoside derivative 6 equipped with a linker at the 2-hydroxy group (Scheme 2). After introduction of the nucleic-acid bases under standard conditions (Scheme 3), the resulting β-D-ribonucleosides 8 and 10 are further transformed to derivatives with lipophilic, intercalating
描述了核糖核苷功能化的一般方法。该方法包括合成在2-羟基上具有连接基的甲基-呋喃呋喃糖苷衍生物6(方案2)。在标准条件下引入核酸碱基后(方案3),将所得的β-D-核糖核苷8和10进一步转化为在连接体部分具有亲脂性,插入性和氨基烷基残基的衍生物。以这种方式,制备了2'-修饰的5-甲基尿苷12,腺苷13以及5-甲基胞苷15和16(方案4)。
