by the biogenetic synthesis of benzofuroindoline‐containing natural products, we designed an oxidative coupling between phenol and N‐acetyl indoles. This straightforward and direct radical process, mediated by 2,3‐dichloro‐5,6‐dicyano‐1,4‐benzoquinone and FeCl3 allowed the regioselective synthesis of benzofuro[3,2‐b]indolines, whose structure is found in the natural product phalarine.
受含苯并呋喃二氢吲哚的天然产物生物遗传合成的启发,我们设计了苯酚和N乙酰基吲哚之间的氧化偶联。由2,3-二氯-5,6-二氰基-1,4-苯醌和FeCl 3介导的这种直接的直接自由基过程允许区域选择性地合成苯并呋喃[3,2-b]二氢吲哚,其结构存在于苯并呋喃中。天然产物法拉灵。
