synthesis of MK-7009, a 22-membered macrocycle, is described. A variety of ring-closing strategies were evaluated, including ring-closingmetathesis, intermolecular palladium-catalyzed cross-couplings, and macrolactamization. Ring closure via macrolactamization was found to give the highest yields under relatively high reaction concentrations. Optimization of the ring formation step and the synthesis of key
