The synthesis of chirally pure β-blockers was successfully achieved via hydrolytickineticresolution of butyl (±)-4-(oxiran-2-ylmethoxy)benzeneacetate ((±)-1) and (±)-4-(oxiran-2-ylmethoxy)benzeneacetonitrile ((±)-2) in the presence of bimetallicchiral [Co(salen)]-typecomplexes. The newly synthesized bimetallicchiral [Co(salen)]-typecomplexes exhibited excellent enantioselectivities of up to >98%
