## Abstract magnified image Efficient syntheses of the title ring systems have been developed from 1__H__‐indole‐2‐butanoic acid, which was easily prepared from 2‐fluoro‐1‐nitrobenzene in four steps. Heating 1__H__‐indole‐2‐butanoic acid in toluene containing __p__‐toluenesulfonic acid at 110°C fu
The carbazole unit of the title molecule, C 15 H 15 NO 3 , is not planar. The dihedral angle between the benzene ring and the fused pyrrole ring is 0.9 (1) . The cyclohexene ring is in a halfchair form. The ester group has an equatorial orientation. In the crystal structure, the molecules are stabil
The relative stereochemistry of the title compound is de®ned by a room-temperature single-crystal X-ray study.
