In this study a series ofnew1-(2-aryl-5-phenethyl-1,3,4-oxadiazol-3(2H)-yl)ethanones 2a-e was synthesized by the cyclization of imines 1a-e using acetic anhydride. The products were evaluated for anti-bacterial and anti-fungal activity. Among the newly synthesized compounds, 1-(2-(4-(dimethylamino)phenyl)-5-phenethyl-1,3,4-oxadiazol-3(2H)-yl)ethanone (2a)and1-(2-(4-chlorophenyl)-5-phenethyl-1,3...

Many organic sulfones have been shown to possess antibacterial, antimalarial, anthelmintic, antilepral, antineoplastic, anti-inflammatory and antidiabetic acitivities. These sulfones are commonly prepared from sodium benzenesulfinate 1-0 which plays an important role in organic synthesis. However the application of 1-0 in solid-phase synthesis has received relatively less attention. This projec...

A short synthetic approach to fused 1,2,5-thiadiazoles from the corresponding 1,2,5-oxadiazoles and 1,2,5-selenadiazoles has been developed. Mono- and bis(1,2,5-thiadiazoles) were selectively obtained in high yields. The pathways for these novel reactions were discussed.

The search for newer non-steroidal antiinflammatory drugs (NSAIDs) and the importance of oxadiazoles as antiinflammatory agents prompted us to undertake the synthesis of some novel oxadiazole and related analogues with unreported antiinflammatory activities. The antiinflammatory potential of the compounds was investigated using the carrageenan-induced rat paw edema method and cotton pellet-indu...

In the title sydnone compound, C(20)H(18)ClN(7)O(4)S, the oxadiazole, triazole, chloro-substituted and meth-oxy-substituted phenyl rings are essentially planar, with maximum deviations of 0.007 (3), 0.009 (2), 0.017 (2) and 0.002 (3) Å, respectively. The dihedral angles between the chloro-substituted phenyl ring and the triazole ring, the triazole ring and the oxadiazole ring, and the oxadiazol...

A new series of 5-(indole-2-yl)-3-substituted 1,2,4-oxadiazoles were synthesized and evaluated for their anticancer activities. Structures of the compounds were confirmed by spectroscopic methods. Structural modifications were done to improve the antiproliferative activity of compound 1. The results indicated that a benzyloxyl substituent on the C-4 position was better than a methyl substituent...

In the title complex, C(8)H(7)N(3)O, the C-O [1.369 (2) and 1.364 (3) Å] and C=N [1.285 (3) and 1.289 (3) Å] bond lengths in the oxadiazole ring are each almost identical within systematic errors, although different substituents are attached to the ring. The phenyl ring is inclined to the planar oxadiazole ring [r.m.s. deviation 0.002 Å] by 13.42 (18)°. In the crystal, molecules are linked via ...
