Stereoselective synthesis of chloramphenicol from D-serine
Tetrahedron Letters, 1998Co-Authors: G. Veeresa, Apurba DattaAbstract:Abstract An efficient synthesis of the widely used antibiotic chloramphenicol ( 1 ) is described. The key step in the synthesis involves chelation-controlled addition of Phenylmagnesium Bromide to a suitably protected D-serinal derivative, affording the pivotal D- threo 1,2-amino alcohol intermediate 3 in a highly stereoselective manner.
