(±)-trans-3-Benzoylbicyclo[2.2.2]octane-2-carboxylic acid
The title keto acid, C(16)H(18)O(3), displays significant twisting of all three ethyl-ene bridges in its bicyclo-[2.2.2]octane structure owing to steric inter-actions; the bridgehead-to-bridgehead torsion angles are 13.14 (12), 13.14 (13) and 9.37 (13)°. The compound crystallizes as centrosymmetric carboxyl dimers [O⋯O = 2.6513 (12) Å and O-H⋯O = 178°], which have two orientations within the ce...
متن کامل(±)-trans-6,7-Dimethoxy-1-oxo-3-(2-thienyl)isochroman-4-carboxylic acid
The title compound, C(16)H(14)O(6)S, was synthesized by the reaction of 6,7-dimethoxy-homophthalic anhydride with thio-phene-2-carbaldehyde in the presence of 4-(dimethyl-amino)pyridine (DMAP) as a basic catalyst. The thio-phene ring of the title mol-ecule is disordered over two sites with occupancies of 0.877 (3) and 0.123 (3). The disorder corresponds to an approximate 180° rotation of the th...

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 کاملtrans-2-(2-Nitro-1-phenylethyl)cyclohexanone
In the title compound, C(14)H(17)NO(3), the plane of the phenyl ring and the least-squares plane of the cyclo-hexyl moiety enclose an angle of 89.14 (6)°. The cyclohexyl ring adopts a chair conformation. In the crystal, the molecules are linked by weak C-H⋯O bonds, with each of the nitro-O atoms accepting two such interactions.
