Ethyl 1,3-dimethyl-1H-indole-2-carboxylate
In the title compound, C13H15NO2, the plane of the indole ring forms a dihedral angle of 5.26 (6)° with the ester group and the ethyl side-chain C atoms. The crystal packing is stabilized by weak intermolecular C—H⋯O and C—H⋯π interactions
3-Bromomethyl-2-chloromethyl-1-phenylsulfonyl-1H-indole
In the title compound, C16H13BrClNO2S, the indole mean plane forms a dihedral angle of 73.59 (19)° with the phenyl ring. The molecular structure is stabilized by weak intramolecular C—H⋯O interactions. The Br atom is disordered over two positions with site occupancy factors of 0.7 and 0.3
Diethyl 2-{[3-(2,4,6-trimethylbenzyl)-1-phenylsulfonyl-1H-indol-2-yl]methylidene}propanedioate
In the title compound, C32H33NO6S, the indole ring system makes dihedral angles of 62.78 (10) and 80.53 (8)°, respectively, with the phenyl and benzene rings. In the crystal, the molecules are linked through intermolecular C—H⋯O hydrogen bonds, forming a chain along the a axis.
