used to synthesize a series of novel analogues of natural product pimprinine. All new compounds were identified by 1H NMR, high resolution mass spectrometry, and the structures of 10 and 18o were further confirmed by X-ray crystallographic diffraction analysis. Bioassay conducted at Syngenta showed that several of the synthesized compounds exhibited fungicidal activity. Compounds 10, 17, 18h, 18o, 19h
已开发出一种简单有效的5-(3-吲哚基)-恶唑合成方案,并进一步用于合成一系列天然产物嘧啶碱的新型类似物。所有新化合物均通过1 H NMR,高分辨率质谱鉴定,并通过X射线晶体衍射分析进一步确定10和18o的结构。在先正达进行的生物测定表明,几种合成的化合物均表现出杀真菌活性。化合物10,17,18小时,180,19H,19I和19升所有这些都显示出以最高筛选率有效控制了7种受试植物病原真菌中的3种。化合物17和19h特别显示出对在人工培养基中筛选的四种病原体的活性。腐霉腐霉,链格孢菌,灰葡萄菌和赤霉菌。
