- 中文摘要: The reaction of 1,4,5,6-tetrahydro-6-pyridazinone-3-carboxylic acid hydrazides (1) with aromatic aldehydes afforded 1,4,5,6-tetrahydro-6-pyridazinone-3-carbonyl aromatic aldehyde hydrazones (2a-2g). Heterocyclic derivatives linked 1,3,4-oxadiazole obtained by cyclocondensation of 2a-2g with acetic anhydride in absolute ethanol, and 2a-2g cyclized with mercaptoacetic acid in DMF in the presence of anhydrous ZnCl2 afforded the 1,3-thiazolidinone derivatives. The structures of the new compounds were established by elemental analyses, IR, 1H NMR and MS spectral data.
