Nill G., 1979: Preparative scale directed resolution of enantiomeric amines via liquid chromatography of dia stereomeric 4 hydroxy butyramides. Angewandte Chemie International Edition In English: 65-66 Racemic 2-substituted butyrolactones, R.noteq. aryl, can be readily resolved into enantiomers by converting them with an enantiomerically pure amine into diastereomeric 4-hydroxybutyramides, separating these by liquid chromatography and cleaving […]
