The diastereomers of dioxindolyl-L-alanine are obtained in a 1:1 ratio by air oxidation of oxindolyl-L-alanine.Preparative separation of the diastereomers is achieved by reverse-phase HPLC.Stereochemistry of the hydroxyl group at C-3 is assigned by transformation to a related pair of diastereomers of known stereochemistry.
