実験手順

5-({[tert-Butyl(dimethyl)silyl]oxy}methyl)-3-[4-(trimethylstannyl)phenyl]4,5-dihydroisoxazole (427 mg, 0.94 mmol), N-{[(5S)-3-{3-fluoro-4-iodophenyl)-2-oxo-1,3-oxazolidin-5-yl]methyl}acetamide (355 mg, 0.96 mmol) and 2-trifurylphosphine (22 mg, 0.094 mmol) were dissolved in dry 1,4-dioxane (10 ml) and the reaction mixture placed under an atmosphere of argon. Tris(dibenzylidineacetone)dipalladium (0) chloroform adduct (49 mg, 0.05 mmol) was added and the reaction mixture stirred for 16 hours at 90° C. A second portion of 5-({[tert-butyl(dimethyl)silyl]oxy}methyl)-3-[4-(trimethylstannyl)phenyl]-4,5-dihydroisoxazole (427 mg, 0.94 mmol), 2-trifurylphosphine (22 mg, 0.094 mmol) and tris(dibenzylidineacetone)dipalladium (0) chloroform adduct (49 mg, 0.05 mmol) were added and the reaction mixture stirred for another 20 hours at 90° C. Silica gel (2 g) was added and the mixture concentrated in vacuo. Purification by column chromatography (20 g silica gel bond elut: 30% to 100% ethyl acetate/hexanes) yielded 170 mg (33%) of the desired compound.
