2-Ethyl-6-(2-pyridyl)-5,6,6a,11b-tetra-hydro-7H-indeno[2,1-c]quinoline

Abstract

The title compound, C23H22N2, was obtained using the three-component imino Diels-Alder reaction via a one-pot condensation between anilines, α-pyridinecarboxyaldehyde and indene using BF 3·OEt2 as the catalyst. The mol-ecular structure reveals the cis-form as the unique diastereoisomer. The crystal structure comprises one-dimensional zigzag ribbons connected via N - H⋯N hydrogen bonds. C - H⋯π inter-actions also occur.
