Abstract An Ir-catalyzed selective mono-sulfamidation of 2-arylquinazolinones has been achieved with a low catalyst loading under mild conditions. A series of regioselective mono-sulfamided 2-arylquinazolinones were obtained in up to 90% yields. Compared with our previous work of constructing di-sulfamidated 2-arylquinazolinones, the mono-sulfamided products could be obtained selectively by changing
摘要在温和条件下以较低的催化剂负载量实现了Ir催化的2-芳基
喹唑啉酮选择性单磺酰胺化反应。以高达90%的产率获得了一系列区域选择性的单磺酰胺化的2-芳基
喹唑啉酮。与我们先前构建二磺酰胺化的2-芳基
喹唑啉酮的工作相比,可以通过改变底物比例,催化剂的负载量,酸添加剂和反应时间来选择性地获得单磺酰胺化的产物。
