    • [5] In order to allow a comparison between calculatory and experimental results, we have performed the calculation on the atropodiastereomer 1a, i.e. with a relative exo configuration [4]. Compound 1 crystallizes as two conformers, both corresponding to the helimeric form 1a, but differing mainly in the dihedral angles α, β, and γ at the biaryl axis (compare Table 1). As an experimental reference structure, the X-ray conformer II (see Table 1) was used which, compared with conformer I, shows distinctly smaller r.m.s. values (by a factor of ca. 0.5) and thus better agreement compared with the calculated minimum structures.
