Conformations of 6aI in solution (NMR, IR) and in the solid state (X-ray) are shown to be similar and it appears, from X-ray data, that the usually invoqued pi-pi* electronic interaction is probably not responsable of the cis conformation. Conformation in solution of the major diastereomer obtained, 3aI, has been shown to be similar to that of 6aI and it is postulate that the asymmetric induction obtained might be due to formation of a bridged species.
