Some derivatives of 5-aryl-, 2.5-diaryl-, and 2-ethoxycarbonyl-5-aryl-indoles are synthesized. Some reactions of ethyl 5-phenylindole-2-carboxylate are described. It is revealed that an - ethoxycarbonyl group has a steric and electron-acceptor influence on indole substitution reactions. The structures of all novel compounds are confirmed by IR, UV, 1 H NMR, 13 C NMR and elemental analyses.
