Abstract

An efficient method for the synthesis of 2-aminoindole-3-carbonitriles and 2-aminoindole-3-carboxylates by the reaction of N-(2-iodophenyl)formamides with malononitrile and cyanoacetates, respectively, in the presence of a catalytic amount of copper(I) iodide using potassium carbonate as a base is reported.

Key words

2-aminoindole-3-carboxylates - 2-aminoindole-3-carbonitriles - N-(2-iodophenyl)formamides - copper(I) iodide - coupling

Before subjection to column chromatography on silica gel, the mixture must be filtered through a small pad of neutral alumina. Omission of this filtration procedure did not give 3a in a satisfactory purity. For details, see the experimental section.
