an azide-bearing N-mustard S-adenosyl-l-methionine (SAM) analogue, 8-azido-5′-(diaminobutyric acid)-N-iodoethyl-5′-deoxyadenosine, has been accomplished in 10 steps from commercially available 2′,3′-isopropylidene adenosine. Critical to this success was executing C8 azidation prior to derivatizing the 5′-position of the ribose sugar and the late stage alkylation of the 5′ amino group with bromoethanol
叠氮基N-芥子S-腺苷-1-蛋氨酸(SAM)类似物8-叠氮基5'-(二氨基丁酸)-N-碘乙基-5'-脱氧腺苷的合成已从10步完成市售的2',3'-异亚丙基腺苷。取得成功的关键是在将核糖的5'-位置衍生化之前进行C 8叠氮化,以及用溴乙醇将5'氨基进行后期烷基化,这是芳基叠氮化物部分的反应性所必需的。带有叠氮化物的N-芥末被设想为一种有用的生化工具,通过它可以探测DNA和蛋白质甲基化模式。
