Direct Conversion of 3-(2-Nitroethyl)-1<i>H</i>-Indoles into 2-(1<i>H</i>-Indol-2-yl)Acetonitriles
The recently discovered [4+1]-spirocyclization of nitroalkenes to indoles provided a convenient new approach to 2-(1<i>H</i>-indol-2-yl)acetonitriles. However, this reaction was complicated by the formation of inert 3-(2-nitroethyl)-1<i>H</i>-indole byproducts. Herein, we off...

description | The recently discovered [4+1]-spirocyclization of nitroalkenes to indoles provided a convenient new approach to 2-(1<i>H</i>-indol-2-yl)acetonitriles. However, this reaction was complicated by the formation of inert 3-(2-nitroethyl)-1<i>H</i>-indole byproducts. Herein, we offer a workaround this problem that allows for effective transformation of the unwanted byproducts into acetonitrile target molecules. |
