摘要
An OJ-H chiral column has been used for direct resolution of the enantiomers of betaxolol and related intermediates in the preparation of (S)-betaxolol. The enantiomers can be excellently resolved (R (S) > 2) within 9.4 min with high peak symmetry. The enantiomers of some acetylated intermediates, which cannot be resolved on an OD-H column, can also be resolved. The method is simple and suitable for routine determination of ee values in the preparation of (S)-betaxolol.
