Synthesis and Fungicidal Activities of 1-(5-Methylisoxazoyl-4-carbonyl)-4-arylsulfonyl Thiosemicarbazides

Abstract

1-(5-Methylisoxazoyl-4-carbonyl)-4-arylsulfonyl thiosemicarbazides, which were prepared by treatment of arylsulfonyl hydrazine with 5-methyl-isoxazole-4-carbonyl isothiocyanate in good yields. The structures of all compounds were confirmed by ¹H NMR, MS and elemental analyses. The preliminary bioassays indicated that some compounds are comparable to the commercial fungicides. Some of these compounds also exhibit moderate fungicidal activities
