An efficient and one-pot method for synthesis of 2-alkylthio-1,3,4-oxadiazole derivatives in mild conditions is described. Some novel derivatives such as bis-1,3,4-oxadiazole analogs are also synthesized.

A new method has been developed for the synthesis of acylhydrazines 5a-g by the reduction of unsymmetrical 1,3,4-oxadiazoles 4a-g by using sodium borohydride/acetic acid combination. Later on, acylhydrazines 5a-g were converted to their corresponding sulfonamide derivatives 6a-d.

The reaction of 5-aryl-1,3,4-oxadiazoline-2(3H)-thiones with alkyl haloacetates has been studied. It was shown that the reaction proceeds to give S-substituted products. The effect of the nature of the substituents in the molecules of both the thiones and the haloacetates on the reaction route and yields has been examined.
