literature precedent, we hypothesized that the diosphenol 7 (assigned here the trivial name myrocin G) is the biologically active form of the representative isolate (+)-myrocin C (1). To probe this, we developed a short enantioselective route to 7. A powerful fragment-coupling reaction that forms the central ring of the target in 38% yield and in a single step was developed. In support of our hypothesis, 7 was
已提出称为 myrocins 的抗增殖抗微生物真菌代谢物通过双核苷酸添加来交联 DNA。然而,DNA 反应性物质的性质是不明确的,因为 myrocins 已被分离为功能不同的 5-羟基-γ-内酯和二酚异构体。根据文献先例,我们假设 diosphenol 7(此处指定为 myrocin G)是代表性分离物 (+)-myrocin C (1) 的生物活性形式。为了探索这一点,我们开发了一条短的对映选择性路线 7。开发了一种强大的片段偶联反应,该反应以 38% 的产率在一个步骤中形成目标的中心环。为了支持我们的假设,7 被有效地转化为双(硫化物)6,这是一种先前从 1 与过量苯硫醇的反应中分离出来的产物。
