以乙酰乙酸乙酯的二硫缩醛为原料,分别合成了1-磺酰基-3-甲基-4-乙氧基(二乙氨基)羰基-5-甲硫(甲磺酰)基-1H-吡唑和1-甲酰基-3-甲基-4-乙氧基羰基-5-甲硫基1H-吡唑。元素分析、1^HNMR证实了它们的结构,部分化合物经过MS和IR的证实。初步的生测结果表明部分化合物对芦笋茎枯病和番茄早疫病具有较好的效果。

In search of novel pyrazole derivatives with bioactivity, three series of 3-methyl-4-ethoxyl(diethylamino) carbonyl-1H-pyrazole derivatives were synthesized via α -oxoketene dithioacetals as starting material. The structures of all compounds prepared were confirmed by 1^H NMR, and elemental analyses, some were confirmed by IR and MS. Preliminary bioassays indicated that some compounds showed fungicidal activity against phoma asparagi.
