The relation between the separability and the stereochemistry of the acylurea derivatives prepared from chiral mono-, bi- and tricyclic acids and N,N′-bis((S)-1-phenylethyl)carbodiimide were investigated. Conventionally separated diastereomers by silica gel column chromatography were converted to optically pure methyl esters of the corresponding acids upon methanolysis.
