Titanium tetrachloride mediated dialkylation of methyl 4-p-bromophenyl-4-oxobutanoate ethylene ketals 2 by 1,8-bis(trimethylsilyl)-2,6-octadiene 1 (BISTRO) led to a mixture of methyl dl and meso-3-(1-p-bromophenyl-2,5-divinylcyclopentan-1-yl)-propanoates 3. Iodolactonisation, reduction with Bu3SnH, Jones oxidation, methoxycarbonylation, alkylation by iodobenzocyclobutene, demethoxycarbonylation and then pyrolysis led to the title compounds.
