Versuchsvorschrift
6.2 G (37.8 mmole) of the carbinol obtained as indicated under letter i. above, dissolved in 50 ml of cyclohexane, were hydrogenated at atmospheric pressure in the presence of 120 mg of Lindlar type palladium catalyst. After filtration and evaporation, the obtained residue was chromatographed on a silica column, using as eluting agent a mixture of 1 to 10% ethyl acetate in cyclohexane, to give 5.9 g (yield: 95%) of undeca-2Z,5Z-dienol.
