Ethyl 4-Oxo-2,3,4,9-Tetra­Hydro-1H-Carbazole-3-Carboxyl­Ate

Abstract

In the title compound, C15H15NO3, the carbazole skeleton includes an eth­oxy­carbonyl group at the 3-position. In the indole ring system, the benzene and pyrrole rings are nearly coplanar, forming a dihedral angle of 0.89 (4)°. The cyclo­hexenone ring has an envelope conformation. In the crystal, inter­molecular N—H⋯O and C—H⋯O hydrogen bonds link the mol­ecules into a three dimensional network. A weak C—H⋯π inter­action is also observed.
