Three new 1,3,4-oxadiazole, 1,3-thiazolidine and 1,2,4-triazole derivatives were obtained starting from furan-2-carbohydrazide. Then, 1,2,4-triazole compound was converted to the corresponding Mannich bases using several secondary amines including piperidine, piperazine, morpholine or thiomorpholine moiety. The synthesis of 5-(furan-2-yl)-4-{[(4-methoxyphenyl)methylidene]amino}-4H-1,2,4-triazole-3-thiol (XIII) was performed starting from furan-2-carbohydrazide by three steps. The structures of the synthesized compounds were well characterized by elemental analyses, IR, H-1 NMR, C-13 NMR and mass spectral studies. Newly synthesized compounds were screened for their antimicrobial activities and some of them displayed activity against the tested microorganisms.
