Abstract 4-Thiochromane-2-carboxylic acid derivatives(2a~2d) were prepared by Michael addition reaction of substituted thiophenol with maleic anhydride. 2-(5-amino-1,3,4-thiadiazol-2-yl)thiochroman-4-one derivatives(3a~3d) were prepared by acylation reaction of 2a~２2d with thiosemicarbazide, respectively. Fourteen novel thiochromanone derivatives(5a~5n) containing 1,3,4-thiadiazole were synthesized by reaction of 3a~3d with acyl chloride. The structures were characterized by 1H NMR, 13C NMR and HR-ESI-MS. The antifungal activities of 5a~5n were investigated by micro dilution method. The results showed that some derivatives exhibited better antifungal activities on Epidermophyton floccosum and Mucor racemosus than Fluconazole.
