New functionalized terphenyl derivatives incorporating various heterocyclic rings are prepared by using 4,4''-difluoro-5'-hydroxy-1,1':3',1''-terphenyl-4'-carbohydrazide as a key intermediate derived from 4,4'-difluoro chalcone, a versatile synthone. All the derivatives are characterized by (1)H NMR, IR, and mass spectral data. All the synthesized products(More)
The 3-cyclo-hexene units adopt envelope conformations in each of the two independent mol-ecules that comprise the asymmetric unit of the title compound, C(20)H(16)F(2)O(3). The dihedral angles between the two fluoro-phenyl rings are 79.7 (2) and 73.7 (2)° in the two mol-ecules. In one of the mol-ecules, two C-H groups of the cyclo-hexene ring are disordered(More)
A series of 1,3,5-triaryl-2-pyrazolines 2a–g were synthesized by the reaction of 4,4′-disubstituted chalcone with phenyl hydrazine. All these compounds were characterized by NMR, IR and mass spectral and single crystal XRD data. All the synthesized products were screened for their in vitro antimicrobial, analgesic and antioxidant properties. The docking(More)
A simple and novel route for the synthesis of new terphenyl derivative as well as oxidative aromatization of α,β-unsaturated cyclohexenone to the corresponding phenol derivative is developed. The present work involves the condensation of ethylacetoacetate with 4,4'-difluoro chalcone followed by the aromatization using chloramine-T in acetic acid to yield(More)
A new series of heterocyclic amides were synthesized by the reaction of heterocyclic amines with substituted phenylacetic acids 1 in the presence of EDC.HCl as a coupling agent. The newly synthesized compounds were characterized by IR, NMR, mass spectral, and elemental analysis. All the synthesized compounds were evaluated for their in vivo analgesic,(More)
In the title compound, C13H13NO4, the N-C(=O) bond length of 1.354 (2) Å is indicative of amide-type resonance. The dihedral angle between the mean planes of the benzene ring and oxo-amine group is 36.4 (3)°, while the mean plane of the 2-methyl-idene group is inclined by 84.2 (01)° from that of the oxo-amine group. In the crystal, classical O-H⋯O hydrogen(More)
