General procedure: To a Schlenk flask charged with Grubbs? catalyst 2 (0.42 g,0.50 mmol) and CuCl (0.05 g, 0.50 mmol), compound 14 (or 15, 16)(0.6 mmol) in 10 mL dry dichloromethane was added at room temperature under N2. The resulting mixture was stirred for 40 min at 40 C. After being cooled to room temperature, the reaction mixturewas filtered and the clear filtrate was collected. The solvent from the filtrate was evaporated under vacuum to give a residue. The residue was purified by silica gel chromatography (CH2Cl2:ethyl acetate 2:1 or pentanes: ethyl acetate 3:2 or 1:1) to givethe desired product as a green crystalline solid., 246047-72-3
