Polyoxamic acid 4a is prepared by a short and efficient process in which the key steps are the highly diastereoselective nucleophilic epoxidation of the D-threitol-derived alkene 6 using potassium tert-butylperoxide, followed by reaction of the oxirane 7a with ammonia.
聚氧肟酸4a是通过一个简短而有效的过程制备的,其中关键步骤是使用叔丁基过氧化钾对D-苏糖醇衍生的烯烃6进行高度立体选择性亲核环氧化,然后使环氧乙烷7a与氨反应。
