Preparation of a 13C-labeled isocyanide and its application to the total synthesis of [2-13C]D-ribo-C18-phytosphingosine are described. The synthesis of the labeled phytosphingosine is based on the use of the isocyanide as a 13CH–NH2 precursor in the SmI2-mediated three-component coupling reaction, wherein regio- and stereoselective incorporation of a 13C nuclide in the carbon skeleton is achieved
描述了 13 C 标记的异氰化物的制备及其在 [2-13 C] D-核糖-C18-植物鞘氨醇全合成中的应用。标记植物鞘氨醇的合成基于在 SmI2 介导的三组分偶联反应中使用异氰化物作为 13CH-NH2 前体,其中 13C 核素在碳骨架中的区域和立体选择性掺入实现。
