Ringing the changes: The totalsynthesis of the title compound centers around a novel strategy that employs a nickel(0)–phosphine complex and triethyl borane in an efficient closure of a 14‐membered ring through CC bond formation (see scheme; cod=cyclooctadiene). The synthesis was accomplished in 10 steps and in approximately 9 % overall yield.
改变变化:标题化合物的全合成围绕一种新策略,该策略采用镍 (0)-膦配合物和三乙基硼烷通过 C C 键形成有效闭合 14 元环(参见方案;cod = 环辛二烯)。合成分 10 步完成,总产率约为 9%。
