O-Methyl-l-serine and its derivatives are relevant in peptide synthesis (food, pharmaceuticals, and cosmetics). Opticallyactive O-methyl-l-serine was prepared using a chemoenzymatic method from inexpensive acrylamide. Our method is a four step reaction sequence; bromination of acrylamide; etherification of dibromopropionamide; ammonolysis of α-bromo-β-methoxy-propionamide; enzymatic racemization;

Lacosamide is an important anti-epilepsy drug and O-methyl-d-serine is a relevant intermediate in the synthesis of lacosamide. Opticallyactive O-methyl-d-serine was prepared by using a chemoenzymatic method from inexpensive acrylamide. Our method is a four-step reaction sequence: bromination of acrylamide; etherification of dibromopropionamide; ammonolysis of α-bromo-β-methoxy-propionamide; enzymatic
