gold-catalyzed α-C−H bond functionalization of tertiary amine was achieved via the intermediacy of a reactive α-imino gold carbene. The use of a malonate group exerting electronic, steric and conformational synergistic effects was key to the success of the transformation. The tetrahydro-γ-carboline products could be subsequently oxidized to access structural motifs found in bioactive natural products.
具有挑战性的金催化的叔胺 α-C-H 键功能化是通过反应性 α-亚氨基金卡宾的中介实现的。使用发挥电子、空间和构象协同作用的丙二酸基团是转化成功的关键。四氢-γ-咔啉产物随后可以被氧化以获得生物活性天然产物中发现的结构基序。
