To a solution of bis(tricyclohexylphosphine)benzylidine ruthenium IV dichloride (39 mg, 0.045 mmol) in dichloromethane (150 ml) at reflux was transferred a solution of 2-hex-5-enyloxy-4,6-dimethoxy-benzoic acid hex-5-enyl ester (430 mg, 1.18 mmol) in dichloromethane (100 ml). After 5 hours at reflux, the solvent was removed and chromatography gave the 1,3-dimethoxy-6,7,8,9,12,13,14,15-octahydro-5,16-dioxa-benzocyclopentadecen-17-one (370 mg).
