本文报道了钯催化的2-溴联苯与环氧化物的[4 + 3]环化反应,合成了二氢二苯并[B,d]氧杂环庚三烯。该方法涉及直接C-H和C-O键活化,然后环化,并且具有容易获得的起始材料、宽的底物范围、良好的步骤经济性和良好的可扩展性。
A palladium-catalyzed [4 + 3] annulation of 2-bromobiphenyls and epoxides for the construction of dihydrodibenzo[b,d]oxepines is reported. This approach involves direct C–H and C–O bond activation followed by a ring annulation and features readily available starting materials, a broad substrate scope, good step economy and good scalability.
