    • PURPOSE: Provided is an economically feasible process for synthesizing sphingoid bases, in particular sphingosine, more particularly D-erythro-sphingosine formed from phytosphingosine. CONSTITUTION: The process for synthesizing the sphingoid base represented by formula II comprises the steps: (1) dissolving a starting compound represented by formula III or a salt thereof in a substantially inert solvent; (2) protecting the NH2 group with a NH2 protecting group; (3) activating the C4HR3 group for an elimination reaction with the C5HR4 group; (4) performing an elimination reaction to form a double bond between the C4 and C5 carbon atom; and (5) removing the NH2 protecting group.
    • 目的:提供一种经济上可行的合成鞘氨醇碱基的方法,特别是鞘氨醇,更特别是由植物鞘氨醇形成的D-赤式 - 鞘氨醇。 组成:合成由式II表示的类鞘氨醇碱的方法包括以下步骤:(1)将由式III表示的起始化合物或其盐溶解在基本惰性的溶剂中; (2)用NH2保护基保护NH2基团; (3)活化C4HR3基团与C5HR4基团进行消除反应; (4)进行消除反应以形成C4和C5之间的碳原子的双键; 和(5)除去NH 2保护基。
