Synthesis and acaricidal activity of strobilurin-pyrimidine derivatives
摘要:
Pyriminostrobin, a new acaricide, was discovered in our previous studies. Because introducing fluorine into organic compounds can increase bioactivity, pyriminostrobin was modified as a series of strobilurin-pyrimidine derivatives for biological screening. The compounds were characterized by H-1 NMR, MS and elemental analysis. Preliminary bioassays demonstrated that compounds 7e and 7i exhibited significant control against Tetranychus cinnabarinus (Boisd.) at 0.625 mg L-1, and their acaricidal potencies were higher than pyriminostrobin in a greenhouse. The relationship between structure and acaricidal activity was also studied. (C) 2013 Chang-Ling Liu and Jun-Biao Chang. Published by Elsevier B.V. on behalf of Chinese Chemical Society.
