A new method for the nitrative spirocyclization of alkynes is described. This method involves the oxidative difunctionalization of alkynes initiated by a radical attack pathway using t‐BuONO (tert‐butyl nitrite) combined with water as the nitro source and TEMPO [(2,2,6,6‐tetramethyl‐piperidin‐1‐yl)oxyl] as the initiator, and it represents a new example of oxidative alkyne difunctionalization via the
描述了炔烃硝化螺环化的新方法。该方法涉及使用叔丁基醚(亚硝酸叔丁酯)与水作为硝基源和TEMPO [[2,2,6,6-四甲基哌啶-1-基]的自由基攻击途径引发的炔烃的氧化双官能化。)氧基]作为引发剂,和它代表氧化炔difunctionalization的一个新的例子经由形成ç N / C C键的的硝基烯烃组件容纳单元-螺环。
