The synthesis of (S)-salbutamol is described. By utilizing DKR in the enantiodetermining step, employing Burkholderia cepacia lipase (PS-IM), (S)-acetate ((S)-6) was obtained in excellent enantiomeric excess (98%). The subsequent transformations yielded the salt of (S)-salbutamol with retained stereochemistry.
