N-[3-(4-Fluoro-benz-yl)-2,4-dioxo-1,3-diaza-spiro-[4.5]dec-8-yl]-2-methyl-benzene-sulfonamide
Abstract:
In the title compound, C(22)H(24)FN(3)O(4)S, the cyclo-hexane ring adopts a chair conformation and the five-membered ring is essentially planar, with a maximum deviation of 0.040 (2) Å. The dihedral angles between the five-membered ring and the tolyl and fluoro-benzene rings are 56.74 (12) and 89.88 (12)°, respectively. The two terminal benzene rings make a dihedral angle of 63.53 (12)°. The crystal structure displays inter-molecular C-H⋯O and N-H⋯O hydrogen bonds. An intra-molecular C-H⋯O hydrogen bond also occurs.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
