Improved Method for Preparation of 3-(1<i>H</i>-Indol-3-yl)benzofuran-2(3<i>H</i>)-ones

Improved Method for Preparation of 3-(1<i>H</i>-Indol-3-yl)benzofuran-2(3<i>H</i>)-ones

3-(1<i>H</i>-Indol-3-yl)benzofuran-2(3<i>H</i>)-ones were efficiently accessed via polyphosphoric acid-mediated condensation of 3-(2-nitrovinyl)-1<i>H</i>-indoles with phenols.
