5-Cyclopentyl-2-methyl-3-(3-methylphenylsulfonyl)-1-benzofuran

Abstract

In the title compound, C21H22O3S, the five-membered ring adopts an envelope conformation with the ipso atom deviating by 0.596 (2) Å from the plane through the rest of the ring atoms. The dihedral angle between the mean planes of the benzofuran and m-tolyl moieties is 78.4 (1)°. In the crystal, molecules related by a glide plane are linked via C—H...O hydrogen bonds into chains along the a-axis direction. These chains are in turn connected by C—H...π interactions into layers parallel to the ac plane.
