YieldReaction ConditionsOperation in experiment
GA06 (12.6 mmol) obtained in Synthetic example 1 and 200 mL of diethyl ether were put in a three-necked round bottom flask, n-BuLi (37.4 mmol) and TMEDA (30 mmol) were added at room temperature, and the reaction mixture was stirred for 3 hours. The reaction mixture was cooled to -78C. A solution prepared by dissolving bromine (177 mmol) in 50 mL of diethyl ether was added dropwise. The mixture was stirred for 4 hours. Then, an aqueous sodium thiosulfate solution was added to quench the reaction. The mixture was extracted with diethyl ether three times. The extract was washed with a saturated aqueous sodium chloride solution followed by dehydration over anhydrous sodium sulfate. After the dehydration, the extract was filtered. After distilling the solvent away under a reduced pressure, the filtrate was purified by means of column chromatography (Hexane:Ethyl acetate (AcOEt)=5:1) to give GA07.
To a solution of 7.8 g (67 mmole) of tetramethylethylenediamine in 500 ml of ether stirred under nitrogen was added 30 ml (72 mmole) of 2.4 M n-butyllithium in hexane. The mixture was stirred at 25 C. for 15 minutes. Next, 10.0 g (31.8 mole) of (R)-2,2'-dimethoxy-1,1'-dinaphthyl was added and the mixture was stirred for 3 hours. The suspension was cooled to -78 C. and 15 ml (0.3 mole) of bromine in 50 ml of pentane was added over a 10 minute period. The suspension was then warmed to 25 C. and after 4 hours. About 300 ml of a saturated solution of sodium sulfate in water was cautiously added. The mixture was stirred for an additional 4 hours and shaken with 1 L of chloroform and 1 L of water. Layers formed which were then separated. The organic layer was dried and evaporated under reduced pressure and the residue was dissolved in 40 ml of hot benzene. This solution was then added to an alumina column suspended in cyclcohexane. Product was eluted from the column with a cyclohexane-benzene mixture to give the desired crude dibromide. The combined fractions of the mixture were recrystallized from 250 ml of methylene chloride-pentane to give 9 g of (R)-3,3'-Dibromo-2,2'-dimethoxy-1,1'-dinaphthyl m.p. 174-175 C.

YieldReaction ConditionsOperation in experiment
bis(triphenylphosphine)nickel(II) chloride; In diethyl ether; at 20℃; for 24.2833h;Heating / reflux; GA07 (5.0 mM), Ni(PPh3)2Cl2 (0.51 mM, 0.1 eq.) and diethyl ether (50 mL) were put, in this order, in a dried three-necked round bottom flask (200 mL) under nitrogen atmosphere and stirred. 2,4,6-Triisopropylphenyl MgBr prepared separately was added dropwise over 7 minutes or more at room temperature. After the adding dropwise, the mixture was stirred for additional 10 minutes , and was heated and refluxed for 24 hours. After that, the mixture was cooled to 0C. The reaction was quenched by the addition of 1 N hydrochloric acid and stirring. The reaction mixture was extracted with diethyl ether three times. The combined diethyl ether extracts was washed with brine and dried over anhydrous sodium sulfate. After the drying, the extract was filtered. The filtrate was concentrated to give a crude product, which was used in the subsequent step without purification. The crude product obtained in the previous step and dichloromethane (135 mL) were put, in this order, in a dried three-necked round bottom flask (300 mL) under nitrogen atmosphere and stirred at 0C. A mixture prepared by diluting boron tribromide (23.28 mM, 4.6 eq.) with dichloromethane (23 mL) was added dropwise over 15 minutes or more. After that, the mixture was warmed to room temperature and stirred for 16 hours. After the stirring, the mixture was cooled to 0C. The reaction was quenched by the addition of water. The reaction mixture was extracted with dichloromethane three times. The combined dichloromethane extracts was washed with brine and dried over anhydrous sodium sulfate. After the drying, the extract was filtered. The filtrate was concentrated to give a crude product, which was separated and purified by means of column chromatography to give GC10 (2.04 mM, 41%).
