benzylic centers of asymmetry

Extended studies have been published concerning absolute configuration correlations and interpretation of ORD and CD Cotton effects of aromatic chromophores.14 The quadrant rule for the ‘Lb transition (Kuriyama and co-workers'5), the quadrant rule for the ‘La transition (De Angelis and Wildeman16), and the general helicity and sector rules (Snatzke and co-workers'7) describe the correlations for.

6 On the basis of the spectroscopic and optical data of the dimer (S,S)-(+)-2a, we have to conclude that this compound has the trans form, although there is quite a similarity between our data and the data obtained by the authors cited. The clarification of this point awaits an X-ray structure determination.
