N-[(1,3-Benzodioxol-5-yl)methyl]benzenesulfonamide: an analogue of capsaicin
نویسندگان
چکیده
The title compound, C14H13NO4S, an analogue of capsaicin, differs from the latter by having a 1,3-benzodioxole ring rather than a 2-meth-oxy-phenol moiety, and having a benzene-sulfonamide group instead of an aliphatic amide chain. The five-membered ring is in an envelope conformation with the methyl-ene 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, mol-ecules aggregate into supra-molecular layers in the ac plane through C-H⋯O, N-H⋯O and C-H⋯π inter-actions.

In the title compound, C25H32N4O4, both piperazine rings adopt a chair conformation. One of dioxolane ring systems is essentially planar [dihedral angle = 0.9 (2)°] while the other adopts a slightly disordered envelope conformation, the mean plane of the dioxolane ring being twisted by 3.6 (2)° from that of the benzene ring. The dihedral angle between the benzene rings is 69.9 (5)°. No classica...
