Abstract:Chloramphenicol and thiamphenicol have been enantioselectively synthesized using an asymmetric halohydrin reaction as a key step. In particular, halomethoxylation reaction was used, where O-methyl functions as a hydroxyl protecting group and eliminates an additional protection step.
Keywords:Enantioselective synthesis   (&minus  )-Chloramphenicol   (+)-Thiamphenicol   Asymmetric   Halohydrin reaction
