We have developed a divergent strategy for the synthesis of five- and six-membered lactams via either an amidation of sp3 C-H bonds or electrophilic substitution of arenes via Ir-nitrene intermediates. With the employment of a readily available iridium catalyst in dichloromethane or hexafluoro-2-propanol, a wide range of lactams were synthesized in good to excellent yields with high selectivity.
我们已经开发了一种通过sp3 CH键的酰胺化或Ir-nitrene中间体亲电取代芳烃来合成五元和六元内酰胺的策略。通过在二氯甲烷或六氟-2-丙醇中使用易于获得的铱催化剂,以高至优异的产率和高选择性合成了多种内酰胺。
