A set of selenoamino acids has been efficiently synthesized under smooth conditions by a simple, flexible and modular strategy. In this method, O-mesylated l-serine methyl ester is generated in situ and directly substituted with various selenolate anions to afford selenocysteine, selenolanthionine, and selenocystine derivatives in good yields. Also, a tellurocysteine derivative can be obtained by this method.
通过简单、灵活和模块化的策略,在顺利的条件下高效合成了一组硒代氨基酸。在该方法中,原位生成 O-甲磺酰化 L-丝氨酸甲酯,并直接用各种硒酸根阴离子取代,以良好的产率提供硒代半胱氨酸、硒代羊毛硫氨酸和硒代胱氨酸衍生物。另外,通过该方法可以得到碲半胱氨酸衍生物。
