SYNTHESIS 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...
متن کامل2-Oxo-2-(2-oxo-2H-chromen-3-yl)ethyl diethyldithiocarbamate
In the title compound, C16H17NO3S2, the dihedral angles between the O/C/C/S group and the 2H-chromene ring system and the thio-carbamate group are 14.46 (9) and 83.30 (9)°, respectively. The bond-angle sum at the N atom is 360.0°. One of the methyl C atoms lies above the thio-carbamate plane and one lies below it [deviations = 1.264 (3) and -1.147 (3) Å, respectively]. In the crystal, inversion...
متن کاملDiethyl 2-oxo-3-(2-oxo-2,3-dihydro-1H-indol-3-ylidene)butanedioate
The title compound, C(16)H(15)NO(6), crystallizes with two symmetry-independent mol-ecules in the asymmetric unit. The crystal structure is stabilized by inter-molecular C-H⋯O and N-H⋯O hydrogen bonds, and intra-molecular C-H⋯O hydrogen bonds. In addition, the crystal structure exhibits two inter-molecular C-H⋯π inter-actions.
متن کامل2-Oxo-2-(2-oxo-2H-chromen-3-yl)ethyl pyrrolidine-1-carbodithioate
There are two independent mol-ecules in the asymmetric unit of the title compound, C16H15NO3S2, in which the pyrrolidine rings adopt envelope conformations, with a methyl-ene C atom as the flap. The dihedral angles betweeen the near-planar 2H-chromene ring systems [maximum deviations = 0.0167 (20) and 0.0136 (19) Å] and the pyrrolidine rings (all atoms) are 83.83 (11) and 82.43 (11)°. In the cr...
متن کاملrac-2-[2-(4-Fluorophenyl)-2-oxo-1-phenylethyl]-4-methyl-3-oxo-N-phenylpentanamide
The title compound, C(26)H(24)FNO(3), is a critical inter-mediate of a selective and competitive inhibitor of the enzyme 3-hy-droxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase. Inter-molecular N-H⋯O hydrogen bonding generates a chain along [give direction] that is the dominant inter-action in the crystal packing. Inter-molecular C-H⋯O inter-actions are also observed.
