Olefin Metathesis: Remote Substituents Governing the Stereoselectivity of 11-Membered-Ring Formation
摘要:
[GRAPHICS]Stereospecific RCM reaction of 7 (R-1 = Me) results in the formation of (Z)-11-membered macrocycle 9c. Cascade RCM/ROM/RCM transformation of 7 (R-1 = H) affords the thermodynamically more stable spirocycle product 12.
