Abstract:
A simple, convenient and straightforward synthesis of 3-aryl-1,2,4-oxadiazoles 4a-f from arylamidoximes 1a-f and palmitic acid 2 is described. Compounds 4a-f are non-lethal in mice at four times the therapeutic dose (i.p., LD50>1 g kg(-1) of the animals' body weight). These heterocycles have been found to possess antiinflammatory property similar to aspirin and ibuprofen. Three compounds, viz., 4a, d, e have also been evaluated for antitumor activity, where 4d exhibited an excellent activity comparable to lapachol.

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
