Abstract: A new series of spiro 1,2,4-triazoles 5-9a-j were prepared by the reaction of appropriate amidrazones 4 with cyclic ketones in catalytic amount of p-toluene sulfonic acid. The structures of the titled compounds have been elucidated by the elemental analysis and spectroscopic data (IR, 1H NMR, 13C NMR and MS). The biological activities of the prepared compounds were investigated using well-established methods from the literature.
