    • PURPOSE: A new oxazole derivative obtained by using amide as a starting material is provided which has a strong antibacterial effect on plant pathogenic bacteria with a small amount, for example Pyricularia oryzae Cavera, Rhizoctonia SolaniAG-1, Botrytis cinerea KCI, Phytophthora infestans or the like. CONSTITUTION: An amid compound(formula II) is refluxed in a solvent of dichloroacetone and ethanol to give chloromethyl oxazole(formula III). A chlorine atom of the chloromethyl oxazole is substituted to an iodine atom by use of sodium iodide and then reacted with 2-(2-hydroxyphenyl)-3-methoxy acrylic acid methylester(formula IV)(in case of A=C) or 2-methoxyimino-(2-hydroxyphenyl)-acetic acid methylester(formula IV)(in case of A=N) to produce an oxazole derivative(formula I).
    • 目的:提供一种以酰胺为原料得到的新型恶唑衍生物,对植物病原菌有较强的抗菌作用,如Pyricularia oryzae Cavera,Rhizoctonia SolaniAG-1,Botrytis cinerea KCI,致病疫霉或 喜欢。 构成:将酰胺化合物(式II)在二氯丙酮和乙醇的溶剂中回流得到氯甲基恶唑(式III)。 氯甲基恶唑的氯原子通过使用碘化钠被取代为碘原子,然后与2-(2-羟基苯基)-3-甲氧基丙烯酸甲酯(式IV)(在A = C的情况下)或2 (2-羟基苯基) - 乙酸甲酯(式IV)(在A = N的情况下)反应以产生恶唑衍生物(式I)。
