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.
