Enzymatic strategies are reported for the synthesis of (2R,3S)-3-amino-2-hydroxy-3-phenylpropionic acid (ee > 98 %), a keyintermediate of the side-chain of Taxol®, by enzymatic hydrolysis in organic media. The newenzymaticcascadereaction, which took place through Candida antarctica lipase B-catalysed deacylation followed by lactam ring-opening of racemic cis-3-acetoxy-4-phenylazetidin-2-one with
