Synthesis of 1, 3-diaryl Substituted Iodobenzene Derivatives

The synthesis and characterization a new derivatives of 2'-iodo-meta terphenyl from the reaction ofexcess aryl-Grignard and 2, 6- dichloroiodobenzene with quenching of m-terphenyl-2'-magnesiumbromide by iodine is reported. Via the reactions three carbon-carbon bonds are constructed and mterphenylsare obtained in good yields.

Regioselectivity of the alkylation of S-substituted 1,2,4-triazoles with dihaloalkanes

BACKGROUND 1,2,4-Triazole3-thiones are good scaffolds for preparation of new lead compounds. Their derivatives attracted the attention of chemists due to their wide spectrum of biological activities. Alkylsulfanyl-1,2,4-triazoles have three nucleophilic sites (nitrogens) ready for reaction with electrophiles. Herein, new regioselective isomers were synthesized by the reaction of benzylsulfanyl-...

Synthesis, Characterization and Biological Evaluation of Novel 1- Substituted-4-(2-methoxyphenyl)-s-triazolo[4,3-a]quinazolin-5(4H)-ones

In the present study a series of 1-substituted-4-(2-methoxyphenyl)-s-triazolo[4,3-a]quinazolin-5(4H)-ones were synthesized and are screened for their H1-antihistaminic activity. The synthesized compounds were characterized by IR, H-NMR and mass spectral data; the purity of the compounds was determined by elemental analysis. Antihistaminic activity of the title compounds was evaluated by histami...
