The Sharpless asymmetric epoxidation was used for the synthesis of both d-erythro-dihydrosphingosine triacetate and (2S,3S,5R)-2-acetamino-5,9-dimethyl-8-decene-1,3-dioL A 13C- NMR study of the latter coupled with biogenetic considerations enabled us to propose (2R*,3R*,5R*,13S*,14R*)-relative stereochemistry for natural aplidiasphingosine. (2R,3R,5R,13R,14R)-(+)-aplidiasphingosine was synthesised starting from (R)-(+)-citronellic acid.
通过对后者的 13C NMR 研究以及生物遗传学方面的考虑,我们提出了天然(2R*,3R*,5R*,13S*,14R*)-(+)-(2R,3R,5R,13R,14R)-aplidiasphingosine 的相关立体化学结构。(2R,3R,5R,13R,14R)-(+)-(R)-香茅鞘氨醇是从(R)-(+)-香茅酸开始合成的。
