4′-Hydroxybiphenyl-4-carboxylic acid
The title compound, C(13)H(10)O(3), has potential oxygen donor and acceptor sites. Inter-molecular hydrogen bonding between neighboring carboxyl-ate groups leads to the formation of hydrogen-bonded dimers [graph-set motif R(2) (2)(8)]. A second hydrogen-bonding inter-action between the hydr-oxy groups generates a chain and extends the structure into a lamellar layer. One of the benzene rings is...
متن کامل6-Fluoro-4-oxochroman-2-carboxylic acid
The title compound, C(10)H(7)FO(4), is an inter-mediate in the synthesis of the drug Fidarestat, (2S,4S)-2-aminoformyl-6-fluoro-spiro[chroman-4,4'-imidazolidine]-2',5'-dione. The di-hydro-pyran-one ring adopts an envelope conformation with the asymmetric C atom in the flap position. In the crystal, the mol-ecules are linked into zigzag chains along [100] by O-H⋯O hydrogen bonds and C-H⋯π inter-...
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 کامل5-Methylisoxazole-4-carboxylic acid
In the title compound, C(5)H(5)NO(3), the mol-ecule lies on a crystallographic mirror plane with one half-mol-ecule in the asymmetric unit. An intramolecular C-H⋯O inter-action is present. In the crystal, strong inter-molecular O-H⋯N hydrogen bonds result in the formation of a linear chain structure along [100], and there are also weak C-H⋯O hydrogen bonds between the chains which help to stabi...
متن کامل2-[3-Cyano-4-(2-methylpropoxy)phenyl]-4-methylthiazole-5-carboxylic acid pyridine solvate
In the title compound, C(16)H(16)N(2)O(3)S·C(5)H(5)N, the benzene and thia-zole rings of the Febuxostat [2-(3-cyano-4-isobut-yloxy)phenyl-4-methyl-5-thia-zolecarboxylic acid] mol-ecule are almost coplanar [dihedral angle = 2.4 (1)°]. The carboxyl group is coplanar with the thia-zole ring [O-C-C-C and O-C-C-S torsion angles of -0.7 (4) and 0.6 (3)°, respectively]. The pyridine mol-ecule of cryst...
