Earlier investigations showed that cycloalkyl N-phenylcarbamates were hydroxylated by the fungus Beauveria bassiana predominantly in the 4-position relative to the electron-rich substituent. In cases involving fluorinated methylene groups potentially capable of hydroxylation, however, defluorination and formation of a ketone was observed. The formation of the ketone can be explained by primary hydroxylation to forman unstable geminal fluorohydrin, which is subsequently dehydrofluorinated. Wiley-VCH Verlag GmbH & Co.

A series of novel 2, 5-disubstituted 1, 3, 4-Oxadiazole derivatives as a potential anti-inflammatory, and anti-oxidant agent were synthesized via cyclisation. Hydrazide molecule treated with substituted acids in the presence of phosphorus oxychloride (POCl3) as an efficient reagent as well as solvent by conventional method with shorter reaction time and excellent yield. The newly synthesized 1, 3, 4- oxadiazole derivatives exhibited excellent to good anti-inflammatory and anti-oxidant activities compaired to the standard drugs. Molecular docking study on the crucial anti-inflammatory target–cyclooxygenase-2 (COX-2) revealed the ability of the scaffold to correctly recognize the active site and achieve significant bonded and non-bonded interactions with key residues therein. This study could identify potential compounds which can be pertinent starting points for structure-based drug design to obtain newer anti-inflammatory agents.
