Specifically, the macrocyclic skeletons of the targets were forged by ring-closing alkyne metathesis (RCAM) or enyne-yne metathesis of suitable diyne or enyne-yne precursors, respectively. This transformation was best achieved with the aid of [(tBu)(Me(2)C(6)H(3))N](3)Mo (37) as precatalyst activated in situ with CH(2)Cl(2), as previously described. This catalyst system is strictly chemoselective for
