Abstract: For finding excellent acaricide, a series of novel 2-acyl-cyanoacetic acid derivatives was designed and synthesized based on cyflumetofen. Their structures were confirmed by 1H NMR, IR and elemental analysis. Preliminary biological evaluation showed that several compounds had acaricidal activity, with compounds 4e and 4k having 100% control against Tetranychus cinnabarinus at 600 mg/L. Some compounds exhibited fungicidal activity and herbicidal activity, compounds 4k and 4s could completely control against Blumeria graminis at 400 mg/L, compound 4m had good control of Abutilon theophrasti at 1000 mg/L. The relationship between the structures and the biological activity was also discussed.

Key words: 2-Acyl-cyanoacetic acid derivative, Acaricidal activity, Fungicidal activity, Herbicidal activity
