Abstract
McMurry cyclisation of 1,4-bis(3-acetyl-4-methoxyphenyl)butane afforded flexible 4,16-dimethoxy-1,2-dimethyl[2.4] metacyclophan-1-ene, which was converted to the corresponding triple bridged 8,17-dimethoxy-1,2-dimethyl-10-thia[2.3.4](1,3,5)cyclophan-1-ene. The conformational studies of these cyclophan-1-enes in solution are also described.
