Key steps in this total synthesis of the antimitotic natural product WF‐1360F (3) include the formation of the macrocycle through ring‐closing alkyne metathesis and the subsequent conversion of the ensuing alkyne moiety into an E‐configured double bond. As illustrated by the synthesis of 4, the macrocyclic vinyl iodide 2 can also serve as a common precursor for the synthesis of side‐chain‐modified
抗有丝分裂天然产物WF-1360F(3)的总合成中的关键步骤包括通过闭环炔烃复分解形成大环,随后将炔烃部分转化为E构型双键。如合成4所示,大环乙烯基碘2也可以用作合成侧链修饰的根霉毒素类似物的常见前体(参见方案; TIPS =三异丙基甲硅烷基)。
