在这里,我们描述了由中心中间体全合成ervaoffine j&k。通过8步合成了Ervaoffine J,收率为14%。我们的策略是采用好氧Winterfeldt氧化来引入4 -喹诺酮类药物。通过10步合成Ervaoffine K,收率为10%。该合成利用(溴代氟甲基)-三甲基硅烷诱导区域选择性von Braun型C - N键断裂。这种C−N键的断裂揭示了ervaoffine K的四取代全同步环己烷核心,并使其合成完成。
Herein, we describe the total synthesis of ervaoffine J & K from a central intermediate. Ervaoffine J was synthesized in eight steps in 14 % yield. Our strategy features an aerobic Winterfeldt oxidation to introduce the 4‐quinolone moiety. Ervaoffine K was produced in ten steps and 10 % yield. The synthesis leveraged (bromodifluoromethyl)‐trimethylsilane to induce a regioselective von Braun‐type C−N bond fragmentation. This C−N bond cleavage unveiled the tetrasubstituted all‐syncyclohexane core of ervaoffine K and enabled the completion of its synthesis.
