چکیده
The title compound, C(13)H(10)BrNO(4)S, belongs to the sulfonamide class of organic compounds. The two aromatic rings are inclined at 34.30 (15)° to one another, and the carboxyl substituent lies in the plane of the benzene ring to which it is bound (maximum deviation = 0.004 Å). In the crystal structure, charactersitic carboxylic acid dimers are formed through O-H⋯O hydrogen bonds. These dimers are linked into rows down a by N-H⋯O inter-actions. Additional C-H⋯O contacts further stabilize the structure, and a close Br⋯Br(x, -y + 1, -z + 1) contact of 3.5199 (9) Å is also observed.

متن کاملPhenylpropanoid Metabolism in Suspension Cultures of Vanilla planifolia Andr. : III. Conversion of 4-Methoxycinnamic Acids into 4-Hydroxybenzoic Acids.
Feeding of 4-methoxycinnamic acid, 3,4-dimethoxycinnamic acid and 3,4,5-trimethoxycinnamic acid to cell suspension cultures of Vanilla planifolia resulted in the formation of 4-hydroxybenzoic acid, vanillic acid, and syringic acid, respectively. The homologous 4-methoxybenzoic acids were demethylated to the same products. It is concluded that the side chain degrading enzyme system accepts the 4...
