FeCl3-catalyzed sequential cyclization for the construction of 12-aryl 5,7-dihydropyrido[2,3-b:6,5-b']diindoles

A facile approach to prepare 12-aryl 5,7-dihydropyrido[2,3-b:6,5-b']diindoles via tandem cyclizations is described. FeCl3 is used as the catalyst for the reaction between o-aminophenylacetonitriles and aromatic aldehydes, generating 5,7-dihydropyrido[2,3-b:6,5-b']diindoles derivatives in moderate to high yields.

Formation of the fused system 5H,7H-pyrido[2,3-b:6,5-b′]diindole from 3-arylidene-2-ethoxyindolenines and hydrazine hydrate

Three 12-aryl-5H,7H-pyrido[2,3-b:6,5-b′]diindoles (Ar = Ph, 4-BrC6H4, and 4-MeOC6H4) were obtained from appropriate 3-arylidene-2-ethoxyindolenines and hydrazine hydrate.
