In an attempt to find the effective phytopesticides, eight novel 4'-substituted benzenesulfonate derivatives of 4-deoxypodophyllotoxin were synthesized and preliminarily tested against the pre-third-instar larvae of Mythimna separata Walker in vivo at the concentration of 1mg/mL. Among all of the
By using podophyllotoxin as a phytoinsecticidal lead compound, 15 novel aromatic esters of 4'-demethyl-4-deoxypodophyllotoxin were semisynthesized and preliminarily tested for their insecticidal activity against the pre-third-instar larvae of Mythimna separata Walker in vivo for the first time.
In an attempt to find biorational insecticides, eleven podophyllotoxin analogues were tested for their insecticidal activity against the fifth-instar larvae of Brontispa longissima in vivo for the first time. Among all of the tested compounds, deoxypodophyllotoxin (3) and beta-apopicropodophyllin
