Ethyl 3-benzoylindolizine-1-carboxylate
Abstract
The title compound, C18H15NO3, consists of an indolizine ring system and an aromatic ring. The two ring systems are not coplanar, the dihedral angle between the two being 54.26 (7)°. In the crystal, inversion dimers are formed by weak C—H...O interactions. These dimeric groups are further extended to form a regular two-dimensional structure by additional weak C—H...O interactions.
