of diverse natural products with complex core structures such as 9,10-deoxytridachione, photodeoxytridachione and ocellapyrone A are derived in nature from a linear and conformationally strained all-(E) tetraene−pyrone precursor. We therefore synthesized such a precursor and investigated its biomimetic transformation under a variety of reaction conditions, both to the above natural products as well as
我们的仿生假说提出,具有复杂核心结构的多种天然产物家族,例如9,10-脱氧三达酮,光脱氧三达酮和ocellapyrone A本质上是从线性和构象应变的全(E)四烯-吡喃酮前体衍生而来的。因此,我们合成了这种前体,并研究了其在多种反应条件下的仿生转化,转化为上述天然产物以及我们认为是“尚待发现”的天然产物的各种异构体。我们还在本文中报道了天然产物iso-9,10-脱氧三丁酮的首次合成。
