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.
描述了一个将(2S,3S)-2-氨基-3-苯基-1,3-丙二醇转化为它们的(2R,3R)-对映异构体的四步过程。最终化合物是有用的中间体,用于合成如氯霉素、甲砜霉素和氟苯尼考等抗生素。起始产品通常是合成上述抗生素时的废弃产品。
