Abstract:

(Chromon-3-yl)bis(indol-3-yl)methanes and E-2-liydroxy-3-(1-methylpyrrol-2-ylmethylene)chroman-4-ones have been obtained in good yields from 3-formylchromones on reaction with indoles and N-methylpyrrole under solvent-free conditions. Reactions of (chromon-3-yl)bis(indol-3-yl)methanes with guanidine carbonate and hydrazine hydrate proceed with the participation of the chromone ring system and lead to the formation of the corresponding pyrimiclines and pyrazoles bearing the bis(indol-3-yl)methyl moiety.
