実験手順
To a solution of ethyl 6-cyano-4,4-diphenyl-hexanoate (5.476 g) in anhydrous THF (195 mL) was added portionwise lithium aluminum hydride (LAH) (1.686 g). A large evolution of gas was observed. The mixture was stirred at rt for 1.5 hr. The reaction mixture was quenched by a careful addition of water (4.5 mL), followed by IN NaOH (4.5 mL) and additional water (15 niL). The mixture was stirred at rt for 10 min and then filtered and the solid was washed three times with THF. The organic filtrates were combined, dried (Na2SO4) and concentrated to give the desired product as a solid foam (4.56 g): MS showed (M+H)+ @ 284; 1H-NMR (CDCl3, δ): 1.05-1.3 (m, 4H), 2.0-2.20 (m, 4H), 2.30-2.42 (t, 2H), 2.82-3.0 (t, 2H), 3.0-3.25 (m, 2H), 3.50-3.65 (t, 2H), 5.10-5.20 (broad m, 1H), 6.86-7.36 (m, 14H).
