synthesis of selenocysteine derivatives and selenocysteine-containing peptides is described. Fmoc-Se-p-methoxybenzylselenocysteine (1) was prepared and used for solid-phase synthesis of peptides with an N-terminal unprotected selenocysteine. Subsequent native chemical ligation with a peptide thioester provided a 17-mer that corresponds to the C-terminus of ribonucleotide reductase with selenocysteine in place
[本文中的反应]描述了合成硒代半胱氨酸衍生物和含硒代半胱氨酸的肽的新方法。制备了Fmoc-Se-对甲氧基苄基硒代半胱氨酸(1),并用于固相合成具有N端未保护的硒代半胱氨酸的肽。随后与肽硫酯的天然化学连接提供了一个17聚体,其对应于用硒代半胱氨酸代替半胱氨酸的核糖核苷酸还原酶的C末端。
