Design, synthesis, and insecticidal bioactivities evaluation of pyrrole- and dihydropyrrole-fused neonicotinoid analogs containing chlorothiazole ring

A series of pyrrole- and dihydropyrrole-fused neonicotinoid analogs containing chlorothiazole ring were synthesized for the first time. The bioassays showed that some of the compounds achieved good insecticidal activity against Aphis craccivora and Nilaparvata lugens.
