the benzofuro[3,2‐b]indoline framework could be obtained by PIDA‐mediated direct oxidative coupling of 2,3‐disubstituted‐indoles with phenols. Application of this chemistry allows for an eight‐step total synthesis of phalarine from commercially available tryptamine.
我们首次报道,可通过PIDA介导的2,3-二取代吲哚与酚的直接氧化偶合获得苯并呋喃[3,2- b ]二氢吲哚骨架。该化学方法的应用使得可以从市售的色胺中进行八步法合成全草胺。

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.
