Sažetak
An almost complete separation of the atropisomers of (I), (II), and ( III) is achieved by liquid chromatography on triacetyl- or tribenzoylcellulose. The barriers to partial rotation about the C-N bond of the enriched enantiomers are determined by thermal racemization and the results are discussed in terms of substituent effects.
