Design, Synthesis and Insecticidal Evaluation of New Daphneolone Analogues as Potential Aphicidal Agents

摘要

@@ Strategy to control pests with classic insecticides, however, may produce side effects, notably environmental contamination and the development of resistant strains. Discovering insecticides with novel structures or mode of actions is one of the effective resistance-management tactics. Natural product is a key and efficient way to discover new agrochemicals with novel structure, low risk to environment. Daphneolones, (E)-l, 5diphenyl-2-penten-1-one (A) and 1, 5-diphenyl-1pentanone (B) extracted from Stellera chamaejasme L.
