4′-Acetyl-3′′-carbamoyl-[1,1′:3′,1′′-terphenyl]-2-carboxylic acid
In the title m-terphenyl derivative, C22H17NO4, the dihedral angles between the aromatic rings of the benzoic acid-acetophenone, acetophenone-benzamide and benzoic acid-benzamide units are 45.39 (8), 48.02 (8) and 42.93 (8)°, respectively. The carbamoyl and carboxyl groups are disordered with a refined occupancy ratio of 0.558 (15):0.442 (15). In the crystal, mol-ecules are linked through O-H⋯O...
متن کاملSYNTHESIS OF 3-ARYLMETHYL-4- THIAZOLIDINE-CARBOXYLIC ACID-2-ONES AND 2-THIONES
Barium salts of dibenzylidene cystines 8a-c were obtained from the reaction of Lcystine with benzaldehyde or its derivatives in the presence of barium hydroxide. Their reduction with zinc and hydrochloric acid in methanol yielded the Narylmethylcysteines ?9a-c?. These can, in turn, be converted by esterification into the methyl esters ?10 a-c. ?Reaction of N, N'-carbonyl diimidazole (Im C...
متن کامل(2S)-3-Carbamoyl-2-(4-methoxybenzenesulfonamido)propanoic acid
In the title compound, C(11)H(14)N(2)O(6)S, an amino acid-derived sulfonamide, the acetamido group and the carb-oxy-lic group are oriented at dihedral angles of 45.84 (5)° and 47.97 (5)° respectively, with respect to the aromatic ring. In the crystal, the mol-ecules are connected by N-H⋯O and O-H⋯O hydrogen bonds and weak C-H⋯O inter-actions, forming a three-dimensional network.
متن کامل4-Sulfenyl-2-carbamoyl-4-isoxazolin-3-ones: biological isostere to 4-chloro-2-carbamoyl-4-isoxazolin-3-ones.
4-Sulfenyl-2-carbamoyl-4-isoxazolin-3-ones (4) were designed on the basis of biological isosterism and prepared in four steps. Some of these compounds showed sufficient pre-emergent herbicidal activities against various kinds of weeds. Among the synthesized compounds, 2-(N-(4-chlorophenyl)-N-isopropylcarbamoyl)-4-ethylthio-5-methyl-4 -isoxazolin-3-one (4cd) exhibited the most promising activity.
متن کامل(2S,3S)-3-(4-Chlorophenyl)-8-methyltropane-2-carboxylic acid
In the title compound, C(15)H(18)ClNO(2), the inter-nal torsion angles of the tropane ring are comparable to those of tropane rings in the crystal structures reported for cocaine and its derivatives. There is an intra-molecular hydrogen bond between the N atom in the tropane ring and the O atom of the carboxyl group. The crystal structure is further stabilized by many weak C-H⋯O inter-actions b...
