Synthesis of 4-aryloxy-7-nitrobenzofurazan Derivatives from 4-chloro-7-nitrobenzofurazan and Various Phenoxide Anions (Including Pharmaceuticals) in the Presence of Crown Ethers
4-Chloro-7-nitrobenzofurazan reacts by nucleophilic substitution with phenoxide anions derived from estriol (2c), ethynylestradiol (2d), phenol (3e), guaiacol (3f ), 2,6dimethoxyphenol (3g), eugenol (3h), isoeugenol (3i), the cytostatic Etoposide (4), and Reichardt’s betaine (5) in the presence of crown ethers a¬ording the corresponding 4-aryloxy7-nitrobenzofurazan derivatives 6c, 6d, 7e { 7i, ...
متن کاملBoron nitride substituted 12-crown-4 ether: Theoretical study of structural, thermochemical, and nonlinear optical properties
The structures and stability of 531 novel boron nitride substituted isomers of 12-crown-4 etherverified theoretically. For a collection of 23 selected BN isomers, structural geometry, vibrationalstability, energy gaps, natural bond population analysis, and nonlinear optical responses investigatedtheoretically. The changes of standard enthalpies for ionization reactions and electron affinityreac...
متن کاملMicrowave assisted synthesis of [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazine Derivatives
New pyrimido [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazines were synthesized via the cyclocondensation of alkyl-2-phenylhydrazinecarbodithioates as a binucleophile with 5-bromo-2,4-dichloro-6-methylpyrimidine as a bielectrophile , and replacement of C-7 chloro atom by hydrazine in ethanol as the solvent . This method has advantages over methods currently described in the literature for the con...
متن کاملSynthesis and Evaluation of Ethyl 2,4-dioxo-4-arylbutanoate Derivatives as Src Kinase Inhibitors
In this work, different ethyl 2,4-dioxo-4-arylbutanoate derivatives were prepared and evaluated for their Src Kinase inhibitory activity. For this purpose, the appropriate substituted acetophenone derivatives reacted with diethyl oxalate in the presence of sodium ethoxide in dried ethanol to give the corresponding products. All compounds showed moderate activities comparing with staurosporine a...
متن کاملEthyl 8-(4-nitrophenyl)imidazo[1,2-a]pyridine-7-carboxylate
In the title compound, C(16)H(13)N(3)O(4), the imidazo[1,2-a]pyridine and benzene rings make a dihedral angle of 56.21 (2)°. The crystal packing is stabilized by weak π-π stacking inter-actions [centroid-centroid distances = 3.787 (2) Å] and C-H⋯O inter-molecular hydrogen-bonding inter-actions.
