94% | With nickel boride; hydrogen; In methanol; at 25℃; for 1.5h; | General procedure: Sodium tetrahydridoborate, 0.46 g (12.1 mmol), was added in portions with stirring to a solution of 1.10 g (4.63 mmol) of NiCl2·6H2O in 20 mL of methanol, cooled to 0 C. The resulting suspension was stirred for 15 min at 0 C and refluxed for 20 min under argon. The mixture was then cooled to room temperature, 9.25 mmol of ketone 1a-1g was added, and the miixture was stirred in a hydrogen atmosphere. When the green color of the reaction mixture disappeared, hydrogen supply was turned off, and the mixture was filtered. The precipitate of nickel boride was additionally washed with a small amount of methanol, and the filtrate was evaporated under reduced pressure. The residue was dissolved in ethyl acetate (20 mL), the solution was washed with a saturated aqueous solution of ammonium chloride (20 mL), the organic phase was separated, and the aqueous phase was extracted with ethyl acetate (10 mL). The combined organic phases were washed with saturated solutions of NaHCO3 and NaCl (10 mL each), dried over Na2SO4, and evaporated under reduced pressure. The residue was purified by crystallization from appropriate solvent mixture or by column chromatography. |
