features broad substrate scope and good tolerance of functional groups and uses molecular oxygen as the terminal oxidant. The high efficiency of the approach is verified by concise total synthesis of natural product cannabinol.
首次报道了钯催化的两个简单的芳烃分子内CH-H / CH-H偶联反应,生成6 H-苯并[ c ]苯并二甲基苯。该方法具有广泛的底物范围和对官能团的良好耐受性,并使用分子氧作为末端氧化剂。天然产物大麻酚的简明全合成证明了该方法的高效率。
