title: Rearrangement of chloramphenicol-3-monosuccinate.
abstract: The equilibrium mixture of chloramphenicol-3-monosuccinate and its alternate form at neutral pH in aqueous solution was reexamined. The structure of the alternate form was shown by mass specxtrometry and NMR spectroscopy to be chloramphenicol-1-monosuccinate and not the cyclic hemi-ortho ester reported previously.
