In order to develop novel spirocyclic tetronic acid lead compounds, twenty-one derivatives of spirocyclic tetronic acid were synthesized from the key intermediate of Spirodiclofen, 3-(2,4-dichlorophenyl)- 4-hydroxy-1-oxaspiro[4.5]dec-3-en-2-one. The structures of all derivatives were confirmed by 1H NMR, ESI MS techniques and elemental analysis. The LD50 of compounds 5g and 5m are 35.12 and 22.39 mg/L against Tetranychus cinnabarinus, respectively, which are better than 45.20 mg/L of Spirodiclofen. The LD50 of compound 5b is 21.90 mg/L against Aphis fabae, whereas the LD50 of Spirodiclofen is 174.13 mg/L.
