influence of the substitution on indolylmagnesium salts in the reaction with benzoyl chlo ride, acrylonitrile and methyliodide, giving the C- and N-derivatives, have been carried out. The yield in the C- and N-product depends upon the electronic character and position of the substituent (methyl or phenyl) on the indole ring and of the ethereal solvent as well as the concentration and molar ratio of the reagents

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。
Synthesis of benzofuro[3,2-b]indolines via regioselective electrooxidative coupling of indoles and phenols
A green and regioselective electrooxidative coupling reaction between indoles and phenols for the synthesis of benzofuro[3,2-b]indolines was developed. A variety of benzofuro[3,2-b]indolines were prepared in moderate to excellent yields. A plausible mechanism was proposed.

The (3 + 2) cycloaddition of various indoles with a dithioallyl cation affords dearomatized cyclopentannulated adducts, with complete control of regioselectivity and excellent chemo- and diastereoselectivity. The success of the reaction critically relies on the use of an excess of very strong Brønsted acid, which paradoxically prevents carbocationic side reactions. The reaction tolerates sensitive
