A new simple approach to 3-(2-acylvinyl)-2-(hetero)aryl-indoles has been developed. The method is based on the acid-catalysed interaction of 2-(2-aminophenyl)furans with (hetero)aromatic aldehydes. The reactions proceed under very mild conditions and

The recyclization of (2-aminophenyl)bis(5-tert-butyl-2-furyl)methanes under acidic conditions was studied. It was found that the extent of reaction of these substrates depends on the substituent at the nitrogen atom of the aniline moiety. N-Tosyl der
