strategies for the diastereoselective total synthesis of schindilactone A (1) are presented and methods for the synthesis of the ABC, FGH, and CDEF moieties are explored. We have established a method for the synthesis of the ABC moiety, which included both a Diels–Alder reaction and a ring‐closing metathesis as the key steps. We have also developed a method for the synthesis of the FGH moiety, which involved
schindilactonetone A(1的非对映选择性全合成的第一代合成策略),并提出了合成ABC,FGH和CDEF部分的方法。我们已经建立了合成ABC部分的方法,其中包括Diels-Alder反应和闭环易位作为关键步骤。我们还开发了一种合成FGH部分的方法,该方法涉及使用Pauson-Khand反应和羰基环化反应作为关键步骤。此外,我们通过使用[3,3]重排作为关键步骤,实现了中央7-8双环系统的构建。然而,不幸的是,当将该重排反应应用于更高级的CDEF部分的构建时,预期的环化反应并未发生,并且需要替代的合成策略来开发该中心核。
