N-[(1,3-Benzodioxol-5-yl)methyl]benzenesulfonamide: an analogue of capsaicin

Abstract

The title compound, C14H13NO4S, an analogue of capsaicin, differs from the latter by having a 1,3-benzodioxole ring rather than a 2-methoxyphenol moiety, and having a benzenesulfonamide group instead of an aliphatic amide chain. The five-membered ring is in an envelope conformation with the methylene C atom lying 0.221(6)Å out of the plane formed by the other four atoms. The dihedral angle between the phenyl ring and the mean plane of the 1,3-benzodioxole fused-ring system is 84.65(4)°. In the crystal, molecules aggregate into supramolecular layers in the ac plane through C - H⋯O, N - H⋯O and C - H⋯π interactions.
