Ethyl 3-[2-benzyl-1-(phenylsulfonyl)-1H-indol-3-yl]acrylate

Abstract

In the title compound, C26H23NO4S, the planes of the ethyl acrylate group, the sulfonyl-bound phenyl ring and the benzyl phenyl group are inclined at angles of 7.91 (4), 81.39 (4) and 88.33 (4)°, respectively, with respect to the indole ring system. The conformations of the phenyl­sulfonyl and benzyl substituents with respect to the indole ring system are influenced by intra­molecular C—H⋯O and C—H⋯π inter­actions. Inversion-related mol­ecules at (x, y, z) and (−x, 1 − y, −z) are linked into a centrosymmetric dimer by C—H⋯O hydrogen bonds. The dimers are crosslinked through C—H⋯π inter­actions, forming a two-dimensional network parallel to the bc plane. Weak π–π stacking inter­actions are present between the phenyl rings of the benzyl groups; the centroid-to-centroid distance between the rings is 3.8027 (9) Å and the perpendicular distance is 3.743 Å.
