N,1-Bis(4-chloro-2-methylbenzyl)-3-methyl-2-oxo-1,2,3,4-tetrahydroquinoline-3-carboxamide
In the title mol-ecule, C(27)H(26)Cl(2)N(2)O(2), the chloro-substituted benzene rings make dihedral angles of 83.29 (9) and 80.81 (9)° with the benzene ring of the tetra-hydro-quinoline group. The dihedral angle formed by the two chloro-substituted benzene rings is 40.87 (12)°. The six-membered N-containing ring is in a half-chair conformation. In the crystal structure, inter-molecular N-H⋯O hy...
متن کاملPotassium (1R,4R,5S,8S)-4,5,8-trihydroxy-3-oxo-2,6-dioxabicyclo[3.3.0]octane-4-sulfonate dihydrate
The title salt, K(+)·C6H7O9S(-)·2H2O, formed by reaction of dehydro-l-ascorbic acid with potassium hydrogen sulfite in water, crystallizes as colourless plates. The potassium ion is coordinated by eight O atoms arising from hy-droxy or sulfonate groups. The sulfonate group is bonded to the C atom neighbouring that of the lactone carbonyl group. As is commonly observed in crystalline l-ascorbic ...
متن کامل(1S,2S,5S)-2-Methyl-3-oxo-5-(prop-1-en-2-yl)cyclohexane-1-carbonitrile
The mol-ecule of the title compound, C11H15NO, contains a cyclo-hexa-none ring, three defined stereocenters and an exocyclic double bond. The crystal structure is the result of a study on the Michael addition reaction of (S)-carvone with sodium cyanide using ionic liquids as the reaction medium and so the absolute configuration is known from the chemistry. The six-membered ring is in a chair co...

In the title compound, C(15)H(11)NO(4), the dihedral angle formed by the benzene ring and isobenzofuran ring system is 67.82 (5) Å. The crystal structure is stabilized by inter-molecular O-H⋯O and N-H⋯O hydrogen-bonding inter-actions.
متن کاملSYNTHESIS AND PHARMACOLOGICAL EVALUATION OF 6-CARBETHOXY-5-(3'-BROMOPHENYL)-3-ARYL-2-CYCLOHEXENONES AND 6-ARYL-4-(3'-BROMOPHENYL)-3-OXO-2,3A,4,5-TETRAHYDRO-2H-INDAZOLES
6-Carbethoxy-5-(3'-bromophenyl)-3-aryl-2-cyclohexenones 2a-j were obtained from the1-Aryl-3-(3'-bromophenyl)-2-propene-1-ones 1a-j by Micheal addition of ethyl acetoacetate, followed by internal Claisen condensation. Reaction of 2a-j with hydrazine hydrate afforded the corresponding 6-Aryl-4-(3'-bromophenyl)-3-oxo-2,3a,4,5-tetrahydro-2H-indazoles 3a-j. The structures of newly synthesized compou...
