Synthesis and Acaricidal Activity of Aryl-Spirobutyrolactone Derivatives against Spider Mites under Greenhouse and Field Conditions

Abstract: Propesticides play an important role in modern agrochemicals research and development. In the controlling of harmful insects and mites in agriculture, propesticide strategy offers a unique and modern approach to acaricide development. In this study, a series of aryl-spirobutyrolactone pharmacophore based alkylated compounds were synthesized and characterized by 1H NMR and ESI-MS. All of this compounds exhibited excellent acaricidal activities against Tetranychus cinnabarinus at 2.5 mg/L in greenhouse test, and some of them showed better activity than spirodiclofen against eggs of T. cinnabarinus at 0.625 mg/L. In the field trials, compounds (Vc), (Ve) and (Vf) were evaluated against Panonychus ulmi and Panonychus citri at three different concentrations. The results showed that compounds (Ve) and (Vf) have the potential to develop into new proacaricide with further test and toxicity evaluation.

Preparation method of spirodiclofen and intermediate of spirodiclofen

The invention discloses a preparation method of spirodiclofen and an intermediate of spirodiclofen. The intermediate of spirodiclofen is 3-(2,4-dichlorophenyl)-2-oxo-1-oxaspiro[4,5]dec-3-ene-4-ol. Thepreparation method comprises the following steps: ethyl or methyl hydroxycyclohexanoate and 2,4-dichlorophenylacetic acid are esterified under the action of a dehydrating agent and then subjected tocyclization reaction, and 3-(2,4-dichlorophenyl)-2-oxo-1-oxaspiro[4,5]dec-3-ene-4-ol is generated. Compared with a traditional process, the synthesis process has the advantages of relatively short synthesis route, simple treatment process, greatly shortened production cycle, obviously increased total yield, reduced production cost and relatively reduced waste water and waste material emissions, and is environmentally friendly accordingly.
