Abstract


Arylpyrrole compounds Chlorfenapyr (chlorfenapyr) is an American Cyanamid Company Streptomyces Streptomyces fumanus microbial metabolites two ah pyrrole neomycin (Dioxapyrrolomycin) for the pilot developed efficient insecticide miticide. Chlorfenapyr in our country has been widely used in vegetable pests , especially for the diamondback moth, Spodoptera exigua , and three kinds of pests has good control effect. Chlorfenapyr creation process is found to be typical , it can be said that the discovery of a lead compound for the launch of the new varieties of pesticides good materials. For us create a new pesticide research is of great significance. Inspired us to dioxin pyrrole amphotericin as a guide, combined with the existing structure-activity relationships , designed and synthesized five novel azole compounds ; to Chlorfenapyr as a guide, draw arylpyrrole insecticidal acaricidal active compounds structure-activity relationships , designed and synthesized three novel aryl pyrroles . With 1 H NMR, 13 CNMR, IR, MS , elemental analysis , X- crystal diffraction confirmed the structure of the new compounds . Bioassay results showed that most compounds Oriental armyworm , carmine spider mite have shown good activity , there are several types of compounds exhibit excellent activity , in particular a new structure type compounds with insecticidal activity of commercial varieties bromine fipronil fairly .
