标题:基于对映选择性有机催化合成 3-羟基脂肪酸和脂肪 γ-内酯
摘要:3-羟基脂肪酸引起了研究人员的兴趣,因为它们中的一些可能比非羟基化的对应物更有效地与游离脂肪酸受体相互作用,并且它们在血浆中的测定提供了有关线粒体缺陷的诊断信息.我们在此介绍了一种用于 3-羟基脂肪酸不对称合成的便捷通用方法的开发.从长链醛开始,末端环氧化物的对映选择性有机催化合成是我们方法的关键步骤,然后是用乙烯基溴化镁开环.臭氧分解和随后的氧化产生目标产物.macmillan 的第三代咪唑啉酮有机催化剂已用于环氧化物的形成,确保产品具有高对映体纯度.此外,开发了一种在带有羟基的碳原子上掺入氘的途径,从而可以合成氘代衍生物,这可能有助于生物学研究和质谱研究.此外,还探索了与 4-羟基脂肪酸相对应的脂肪 γ-内酯的合成.
