Application
Switching Enantioface Selection in the Asymmetric Nitro-Mannich Reaction Using PyBidine-Metal Catalysts
Typical Procedure (Cat.: Ni(OAc)2 ·4H2O, Ar: Ph): PyBidine (15.5 mg, 0.022 mmol) and Ni(OAc)2 ·4H2O (12.3 mg, 0.02 mmol) are added to a flask under Ar. Dichloromethane (1.00 mL) is added to the flask and the mixture is stirred for 3 hours. After removal of the solvent under reduced pressure, dioxane (1.00 mL) is added as a reaction solvent. To the resulting solution, nitromethane (122 mg, 2.00 mmol), DIPEA (2.6 mg, 0.02 mmol) and tert-butyl benzylidenecarbamate (41.1 mg, 0.20 mmol) are added at r.t. After being stirred for 24 hours, the reaction mixture is quenched by saturated NaHCO3 aq., extracted with dichloromethane, and dried over Na2SO4. After removal of the solvent under reduced pressure, the resulting crude mixture is purified by silica gel column chromatography to give (R)-tert-butyl 2-nitro-1-phenylethylcarbamate (90% yield, 89% ee).
