phenoxy-2-propanol) were synthesized. Key step is the lipase-catalyzed kineticresolution of rac-3-hydroxy esters either by O-acylation using vinyl acetate or by hydrolysis of the ester group. Both approaches were highlyenantioselective (> 95 %ee) with E-values > 150 using lipase from Pseudomonas cepacia. The formal synthesis of (−)-(S)-propranolol was developed in subsequent steps.
