The present invention relates to a process of manufacture of compounds of formula (B) wherein R1, R2 and R3 are as defined for compounds of formula (A), which process comprises hydrogenation of compounds of general formula (A). In particular, the present invention relates to an improved process for the manufacture of Lacosamide (LCM), (R)-2-acetamido-N-benzyl-3-methoxypropion-amide (B1), which is useful as an anticonvulsive drug.

Two new chiral cationic rhodium(I) complexes derived from electron-rich dicyclohexylphosphine-phosphite ligands were prepared from enantiopure Sharpless epoxy ethers. The best-performing catalyst system, which bears a less bulky methyl ether moiety, exhibited remarkably high enantioselectivity (up to 99% ee) and reactivity (up to >2500 TON) in asymmetric hydrogenation reactions of various functionalized
