A model has been developed for predicting the diastereoselectivity in the electrophilic amination of chiral 1,3,2-oxazaphospholanes derived from ephedrine and pseudoephedrine derivatives.The influence of the five-membered ring conformations and of the bulkiness of the ring substituents has been deeply analyzed both for reactivity prediction and for 1H-NMR data interpretation.The theoretical and experimental results are in good agreement.
