Abstract:(3R,3aS,6aR)-Hexahydrofuro[2,3-b] furan neonicotinoid compounds were synthesized through a series of reactions including esterification of(3R,3aS,6aR)-hexahydrofuro[2,3-b] furan-3-ol, SN2 nucleophilic substitution, reduction using palladium on carbon as catalyst and condensation reaction. The choice of esterification reagents and solvent, temperature, time of nucleophilic reaction were optimized in detail in this paper. And the activity tests of resulting compounds on target bean aphid were carried out, and results indicated compound 4 was of the best activity with a mortality rate of 65.96% at a loading of 10 mg/L.
Key words:(3R,3aS,6aR)-hexahydrofuro[2,3-b] furan-3-ol; esterification; nucleophilic substitution; catalytic reduction; activity tests
