Abstract:

In order to explore novel green pesticide with potent biological activities, a series of novel 1,4-pentadien-3-one oxime ester derivatives bearing heterocycle moiety, derived from curcumin, was designed and synthesized. Their structures were confirmed by infrared spectroscopy, proton nuclear magnetic resonance spectroscopy(1H NMR), 13C NMR, and high resolution mass spectroscopy(HRMS). The bioassays indicate that inhibition rates of compound 5d against G.zeae, F.ox-ysporum and C.mandshurica at 50 mg/L are 64.75%, 52.05% and 69.68%, respectively, and compounds 5d, 5e and 5f have good curative and deactivation activities against tobacco mosaic virus at 500 mg/L, with the inhibition rates of 56.93% and 86.89%, 53.08% and 83.51%, and 53.40% and 89.01%, respectively. These indicate that 1,4-pentadien-3-one oxime ester is a valuable scafford to develope new compounds poessessing high biological activities such as potential antifungal and antiviral activities.
