Diethyl 2-[(5-methoxy-2-methyl-1-phenylsulfonyl-1H-indol-3-yl)methylene]malonate

Abstract

In the title compound, C24H25NO7S, the sulfonyl-bound phenyl ring is approximately perpendicular to the indole ring system [dihedral angle = 87.72 (5)°]. The methyl group of one of the ester units is disordered over two positions with occupancies of 0.527 (13) and 0.473 (13). An intramolecular C—H...O hydrogen bond is observed. In the crystal structure, molecules are linked into a ribbon structure running along the c axis by intermolecular C—H...O hydrogen bonds and C—H...π interactions involving the pyrrole ring.
