title: Olefin metathesis: remote substituents governing the stereoselectivity of 11-membered-ring formation.
abstract: [reaction: see text] Stereospecific RCM reaction of 7 (R1 = Me) results in the formation of (Z)-11-membered macrocycle 9c. Cascade RCM/ROM/RCM transformation of 7 (R1 = H) affords the thermodynamically more stable spirocycle product 12.
