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 substitutents has been deeply analyzed both for reactivity prediction and for 1H-NMR data interpretation. The theoretical and
已经开发出一种模型,用于预测衍生自麻黄碱和伪麻黄碱衍生物的手性1,3,2-氧杂氮磷酯的亲电胺化中的非对映选择性。五元环的构象和环取代基的庞大的影响已进行了深入的反应性预测和1 H-NMR数据解释的分析。理论和实验结果吻合良好。
