-
Eight novel fluorine-containing PhTX-12 derivatives were prepared from the intermediate obtained via one-pot Ugi four-component solvent-free reactions by the simple removal of the protecting groups in the presence of trifluoroacetic acid. Their structures were identified by 1H NMR,13C NMR and HRMS or MS. Preliminary bioassays indicate that compound 6b showed 44% and 42% mortality rates against Heliothis armigera and Pieris rapae respectively at a concentration of 100 mg/L.
