Enantiopure (S)-betaxolol was prepared in an extremely simple and practical way using hydrolytic kinetic resolution of a terminal epoxide by Jacobsen's catalyst. High enantiomeric purity (99% ee) has been achieved and the method is amenable to industrial scale-up.

The invention provides phenol ethers of the formula: STR1 wherein R is branched C 3-4 alkyl, C 3-4 cycloalkyl, branched cyano(C 3-4 alkyl), phenyl(C 2-3 alkyl), halophenyl(C 2-3 alkyl), (C 1-4 alkoxy)phenyl(C 2-4 alkyl), or (C 1-4 acyl) amino(C 1-4 alkyl),alk is C 1-4 alkyl substituted by a 3 to 6 membered cycloalkyl group,X is--O--,--S--or--SO 2--; andR 1 is--C 1-4 alkyl-or--C 1-4 alkoxy-, in their racemic and optically active forms, and their addition salts with pharmaceutically acceptable acids. These compounds are useful in therapy as β-adrenergic blocking agents. Intermediates are also provided.
