Oxadiazole derivativesR 0290 An Efficient Synthesis and Biological Study of Novel Indolyl-1,3,4-oxadiazoles as

Potent Anticancer Agents. — The oxidative cyclization of hydrazones (I) is achieved by grinding with [bis(trifluoroacetoxy)iodo]benzene under solvent-free conditions fur-nishing indolyloxadiazoles (II) rapidly in good yields without any by-product. Com-pounds (IIId), (IIIe), and (V) display potent cytotoxicity and selectivity against human cancer cell lines. — (KUMAR*, D.; SUNDAREE, S.; JOHNSON, E. O.; SHAH, K.; Bioorg. Med. Chem.
