Reaktionsschritte

Into a 100-mL stainless-steel autoclave was put 143 mg (1 mmol) of methyl 2-acetamido-2-propenate, 22.6 mg [0.03 mmol (Cu reduced)] of [CuBr((S)-SEGPHOS)]n and 33.6 mg (0.3 mmol) of tBuOK, followed by replacing with nitrogen in the autoclave, and then 1.4 mL of a mixed solvent of toluene and t-BuOH in a ratio of 3:1 was added. The reaction was carried out with stirring under a hydrogen pressure of 3.0 MPa at 85° C. for 17 hours to give methyl 2-acetamidopropionate, which is a hydrogenated compound of methyl 2-acetamido-2-propenate in a yield of 52.5%.
