^a)To a mixture of palladium catalyst, sodium sulfate (100mg, 0.7 mmol), 7 (0.2 mmol), and 8 (0.52 mmol) in 1 mL CH₂Cl₂ in Schlenk tube was added dropwise 9 (0.4 mmol). The mixture was stirred for 24 hrs at room temperature. If necessary, compounds were purified by column chromatography on silica gel with a gradient elution of hexanes/ethyl acetate.

^b)Isolated yields.
