from (e.g. ) in the presence of dimethyldiselenide provided the protected L-selenomethionine directly. We have shown that triselenocyanide Se3(CN)2 can serve as an efficient selenocyanating agent for radicals; the selenocyanide group is a good precursor for the diselenide moiety of L-selenocystine.
L-硒代蛋氨酸和L-硒代胱氨酸分别以高产率从受保护的L-谷氨酸和L-天门冬氨酸衍生物制备。在二甲基二硒化物的存在下辐照衍生自(例如)的混合酸酐(酯)可直接提供被保护的L-硒代蛋氨酸。我们已经表明,三硒氰化物Se 3(CN)2可以作为自由基的有效硒氰化剂。硒氰化物基团是L-硒代胱氨酸的二硒化物部分的良好前体。
