摘要: A novel series of picarbutrazox-inspired oxadiazole hybrids was synthesized and the derivatives’ biological activity against phytopathogenic fungi investigated. The molecules were designed by retaining active fragment tetrazolyl phenyloxime ether lead compound picarbutrazox, while introducing potentially oxadiazole-derived fragment. Bioassay results revealed that some title compounds showed potent in vivo antifungal activities to control cucumber downy mildew. Therefore, this phenyloxadiazole derivative can be used as a potential agent mildew other for crop protection.
