Opticalactive chlorohydrin derivatives 2a-m and 3a-m of both enantiomeric series were prepared via both enzymatic hydrolyses and acyltransfer reactions catalysed by a highly selective lipase from Pseudomonas sp.. The resulting building blocks were further transformed into the corresponding β-blockers of high enantiomeric purity.
