Synthesis insecticidal and antibacterial activities of novel neonicotinoid analogs with dihydropyridine

摘要

BackgroundNilaparvata lugens, a major pest in rice-growing areas, is extremely difficult to manage. Neonicotinoids have increasingly been used in crop protection and animal health care against N. lugens. To discover new bioactive molecules and pesticides, we combined the active structure of cyanoacrylates, aromatic aldehydes, and substituted pyridyl (thiazolyl) methyl-2-substituted-methylidene-imidazolidine derivatives for the design and synthesis of a series of novel neonicotinoid analogs with dihydropyridine.
