  o-Nitrobenzenesulfonamides in Nucleoside Synthesis:  Efficient 5‘-Aziridination of Adenosine

  摘要：

  5'-Aziridinoadenylates of the form 1 and a related nitrogen mustard variant have been constructed using a novel variation of the Mitsunobu reaction. Such molecules allow conversion of biological methyltransferases into nucleoside transferases, thus providing powerful tools for investigating S-adenosyl-L-methionine (SAM)-dependent methylation. We present here a highly effective synthesis of such molecules that is amenable to aziridine diversification as well as elaboration of the base moiety so as to afford "bumped" cofactor mimics compatible with "hole"-bearing mutant proteins.

• Synthesis of an Azide-Bearing <i>N</i>-Mustard Analogue of <i>S</i>-Adenosyl-<scp>l</scp>-methionine

  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。
