The improved synthesis of the antitumor compound (+)‐tedanolide is described through an aldol coupling of bis‐ketone 7. This modification shortens the synthetic steps in the endgame and provides rapid access to this biologically important natural product. Additionally, it serves as a probe in order to unravel the conformational effects that impede or enable its successful synthesis. Having this way
通过双酮7的醛醇偶联描述了抗肿瘤化合物(+)-泰诺醇化物的合成方法的改进。这种修饰缩短了最终过程中的合成步骤,并提供了对这种生物学上重要的天然产物的快速访问。此外,它还可以作为探针来揭示阻碍或使其成功合成的构象效应。通过这种方式获得去环氧-萜内酯,其生物学特性出乎意料地揭示了类似于念珠菌皂苷而不是脱氧乙醇胺的作用方式。
