Procedure

To a solution of 2-vinylnaphthalene (138 mg, 0.89 mmol) in 0.5 mL of THF was added 9-BBN (0.89 mmol, 1 equiv) in THF, at 0°. Let stir for 1 h, warming to 5°. To the mixture was added (+)-(4aR)-(10bR)-4-H-8-bromo-10b-methyl-1,2,3,4,4a,5,6,10b-octahydrobenzo[f]quinolin-3-one (250 mg, 0.812 mmol), triphenyl phosphine, (42 mg, 0.16 equiv.), tetrakis (triphenylphosphine)palladium(0) (19 mg, 0.02 equiv), 1 mL of 3N sodium hydroxide solution and an additional 1 mL of THF. The resulting mixture was heated at 80° for 18 h, cooled, and ethanolamine was added, followed by ethyl acetate. The resulting organic phase was washed with brine, dried over sodium sulfate, concentrated, and purified by silica gel chromatography (50-100% ethyl acetate/hexanes eluent gradient) to give 186 mg (60%) of the title compound as a tan solid. mp 109°-110°. FDMS m/e=383. α[D]589 =+46.45 (c=0.66, chloroform).
