| Abstract: | An efficient chemoenzymatic route to S-betaxolol is reported. A strain (Rhodotorula mucilaginosa DQ832198) screened from soil was used as biocatalyst for the kinetic resolution of the key acetylated intermediates. Excellent enantiomeric excess (ee > 99%) was obtained under very mild conditions. The biocatalyst is quite stable and could be used several times with little decrease of the resolving ability.  Additional information ACKNOWLEDGMENT We acknowledge the National Natural Science Foundation of China for financial support of this work (20572103). |
