The chiral building block (S)-N-benzyl-N-isopropyl-2,3-epoxypropylamine is obtained by means of chlorohydroxylation of allylamine, followed by Jacobsen's hydrolytic kinetic resolution with water. A concise, divergent five-step synthesis of three β-adrenergic blocking agents in high enantiomeric excess using (S)-N-benzyl-N-isopropyl-2,3-epoxypropylamine as the key intermediate is described.
