Abstract
In the presence of chiral camphorsulfonic acid (CSA) the anti and syn atropisomers of the title compound in acetone-d(6) form diastereomeric salts detectable at ambient temperatures by proton NMR. Comparison of these spectra with those generated in the presence of racemic CSA pro vides evidence for the formation of the diastereomers. Copyright (C) 1 996 Elsevier Science Ltd
