Ethyl 2-phenyl-5,6-dihydropyrrolo[2,1-a]isoquinoline-3-carboxylate

Abstract

In the title compound, C21H19NO2, the six-membered heterocycle assumes a screw-boat conformation. The phenyl ring is oriented with respect to the pyrrole ring at a dihedral angle of 64.76 (10)°. An intramolecular C—H...O hydrogen bond helps to stabilize the molecular structure. There are weak C—H...π interactions between inversion-related molecules in the crystal.
