Benzaldehyde → 2-Nitro-1-phenyl-1-propanol

참여 물질

반응 단계

To a solution of benzaldehyde (20.0 g) and nitroethane (28.4 g) in tetrahydrofuran (50 mL) and tert-butanol (50 mL) was added potassium tert-butoxide (1.27 g) under ice-cooling, and the mixture was stirred at room temperature for 16 hr. Water was added to the reaction mixture, and the mixture was extracted with diethyl ether. The extract was washed with saturated aqueous sodium hydrogen carbonate solution and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent:hexane-ethyl acetate=10:1) to give the title compound as a blue oil (yield 32.0 g, 93%).
