The KOH-, K2CO3-, or Et3N-catalyzed ring-opening reaction of N-tosylaziridines using the nitrogen atom of a series of (E)-aldoximes and (E)-ketoximes as a nucleophilic atom instead of an oxygen atom was developed to construct various nitrones under mild reaction conditions. Diverse (E)-aldoximes and (E)-ketoximes were demonstrated to be compatible with this reaction and the products of O-ring-opening reactions were not detected for most examples.
KOH-、K2CO3-或Et3N催化的N-对甲苯磺酰基环氧丙烷的开环反应,使用(E)-醛肟和(E)-酮肟系列化合物的氮原子作为亲核原子,而不是氧原子,以在温和的反应条件下构建各种亚硝酮。多种(E)-醛肟和(E)-酮肟已证明与该反应兼容,并且大多数示例中未检测到O-环开启反应的产物。
