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.
介绍了将 (2S,3S)-2-氨基-3-苯基-1,3-丙二醇转化为其 (2R,3R)-对映体的四步工艺。最终化合物是合成氯霉素、硫霉素和氟苯尼考等抗生素的有用中间体。起始产物通常是合成上述抗生素过程中的废弃产物。
