properly elaborated alkyne fragments, leading to the 1,3,6-triene motif of piericidin A. Utilization of propene as a unique alkene, capable of sequential coupling with two alkynes, is further illustrated in the context of various 1,3,6-triene products. The latter process proceeds with high atom economy and efficiently gives rise to complex frameworks from readily accessible alkyne substrates. This strategic
公开了一种简洁且收敛的哌啶 A 全合成。合成取决于利用丙烯作为合成关键来合并适当精心设计的炔烃片段,从而产生 piericidin A 的 1,3,6-三烯基序。 将丙烯用作独特的烯烃,能够与两个炔烃顺序偶联,在各种 1,3,6-三烯产品的上下文中进一步说明。后一个过程以高原子经济性进行,并从容易获得的炔烃底物有效地产生复杂的框架。这种战略性的 CC 键形成为合成路线的设计提供了正交范式,从而实现更高的步骤经济性和更有效的多不饱和天然产物的合成。
