(2S)-1-O-9-Oxo-(10E,12E)-octadecadienoyl glycerol, a natural anti-melanogenic monoglyceride, is synthesized for the first time. The chiral pool based route employed not only confirms the absolute configuration, but also illustrates the first synthetic entry to the (E,E)-diene keto acid, which is another molecule of biological importance. The confusion caused by the misinterpreted H-1 NMR spectroscopic data for the (E,E)-diene motif in the literature is discussed. The first unequivocal piece of evidence for the assigned (12E) configuration is also presented.
(2S)-1-O-9-氧代-(10E,12E)-十八碳二烯酰基甘油,一种天然的抗黑色素生成单甘油酯,首次被成功合成。本文采用的手性池路线不仅验证了其绝对构型,还展示了通往(E,E)-双烯酮酸的首个合成路径,这一化合物具有重要的生物意义。文中还探讨了文献中由于H-1 NMR光谱数据分析错误对(E,E)-双烯基团造成的混淆。同时,我们首次提出了明确支持(12E)构型的证据。
