Acid hydrazides were coupled with acrylic acid derivatives and cyclodehydration gave 1,3,4-oxadiazoles. Lastly, in-situ nitrile oxide formation from aryl oximes treated with sodium hypochlorite, and subsequent 1,3-dipolar cycloaddition to the exomethylene moiety delivered 2-(4,5-dihydroisoxazol-5-yl)-1,3,4-oxadiazoles. This library was evaluated in a high-throughput screen at Dow AgroSciences. Several
将酰肼与丙烯酸衍生物偶联,并进行环脱水,得到1,3,4-恶二唑。最后,由次氯酸钠处理的芳基肟原位生成一氧化氮,随后将1,3-偶极环加成到亚己基上,得到2-(4,5-二氢异恶唑-5-基)-1,3,4-恶二唑。在Dow AgroSciences的高通量筛选中对该库进行了评估。几种化合物对真菌病原体和害虫具有活性。
