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 lead to indoles containing a reactive α,β-unsaturated ketone moiety, which is suitable for further transformations, in moderate to good yields.

Indolo[3,2-c]quinolines are pharmacologically attractive class of heterocyclic compounds. The method of their synthesis, based on transformation of furfural, which is a large-scale product of treatment of biomass including agricultural and forestry wastes, has been developed. This method was utilized for the total synthesis of antimalarial alkaloid isocryptolepine and its derivatives.
