Procedure
To a solution of 31 (110 mg, 0.22 mmol) in 20 ml of toluene and CH2Cl2 (1:1) at 100 degree was added (bis(tricyclohexylphosphine)-benzylidine ruthenium (IV) dichloride) (24 mg, 0.029 mmol). The mixture was stirred at 100 degree for 4 hrs and another 24 mg Grubbs' catalyst was added. The mixture was then stirred at 100 degree for another 4 hrs. Then the solution was cooled to RT, after which 100 mg of charcoal was added. The mixture was filtered through ceslite to provide a slightly yellow solution, then concentrated. The residue was purified in silica gel chromatography with CH2Cl2/methanol (10:0.5) to give 48 mg of 32 (46%). 1H NMR (CDCl3) 0.97-0.90 (dd, 6H), 1.30-1.25 (m, 1H), 1.65-1.57 (m, 1H), 2.00-1.85 (m, 1H), 2.40-2.30 (d, 1H), 2.80-2.65 (m, 2H), 3.00-2.80 (d, 1H), 3.40-3.20 (m, 1H), 3.47 (s, 3H), 5.40-5.20 (s, 1H), 5.52-5.49 (d, 1H), 5.80-5.71 (m, 2H), 7.63-7.20 (m, 9H), 7.90 (s, 1H). API AP+ 473.1 (M+1).
