Process for the stereochemical inversion of
(2S,3S)-2-amino-3-phenyl-1,3-propanediols into their (2R,3R) enantiomers
摘要:
A four step process for transforming (2S,3S)-2-amino-3-phenyl-1,3-propanediols into their (2R,3R)-enantiomers is described. The final compounds are useful intermediates for the synthesis of antibiotics like Chloramphenicol, Thiamphenicol and Florfenicol. The starting products generally are discard products in the synthesis of said antibiotics.
