PROCESS FOR PRODUCING β-AMINO-α-HYDROXYCARBOXYLIC ACIDS AND DERIVATIVES THEREOF

摘要

Disclosed is a process for producing β-amino-α-hydroxycarboxylic acid derivatives of general formula (2R,3S)- or (2S,3R)-N-(X,Y)-3-amino-2-hydroxy-3-phenyl-propionic acid-Z of formula (I), e.g. of (2R,3S)-3-amino-2-hydroxy-3-phenyl-propionic acid or (2R,3S)-N-benzoyl-3-amino-2-hydroxy-3-phenyl-propionic acid methylester. Compounds of type I are valuable intermediates in the total synthesis of taxols which can be used in the treatment of various forms of cancer.
