d-ribo-C18-phytosphingosine and l-arabino-C18-phytosphingosine were synthesised starting from commercially inexpensive d-fructose. Metal-mediated fragmentation and stereoselective reduction were used as key steps to provide the hydrophilic portion of d-ribo and l-arabino phytosphingosines. Grubbs’ cross-metathesis and hydrogenation allowed the incorporation of hydrophobic tail.
d -核糖-C 18 -phytosphingosine和升-阿拉伯-C 18 -phytosphingosine合成从市售廉价的起始d -fructose。金属介导的断裂和立体选择性还原被用作关键步骤提供的亲水性部分d -核糖和升-阿拉伯phytosphingosines。格拉布斯的交叉复分解和氢化作用使疏水尾部得以结合。
