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 rhizoxin analogues (see scheme; TIPS=triisopropylsilyl).
