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
