Herein, we describe the first total synthesis of fomitellic acid B (2), a potent inhibitor of DNA polymerases α and β. There are two key features in this synthesis: (i) the AB ring system, with all requisite chiral centers, is stereoselectively constructed by means of titanium(III)-mediated radical cascade cyclization of epoxypolyene; and (ii) an enone moiety in the B-ring is generated by isomerization
在本文中,我们描述了Fometellic酸B(2)的第一个全合成过程,后者是DNA聚合酶α和β的有效抑制剂。该合成具有两个关键特征:(i)通过钛(III)介导的环氧多烯自由基级联环化,立体选择性地构建具有所有必要手性中心的AB环系统;(ii)B环中的烯酮部分是通过烯烃的异构化然后进行烯丙基氧化而产生的。
