Versuchsvorschrift
A solution of methyl 2-acetamidoacrylate (22 mg, 0.15 mmol) and the catalyst (I) (1 mg, 0.0015, 1 mol %) in degassed methanol (1 ml) was prepared under exclusion of oxygen in a GC-vial. The vial was placed in a 50 ml Parr reactor which was purged with hydrogen and charged to 3.41 MPa (500 psi). After hydrogenation of the mixture overnight, the solvent was evaporated to give the (R)-N-acetylalanine methyl ester (complete conversion, 62.8% ee).
