Abstract:

Eight novel fluorine-containing PhTX-12 derivatives were prepared under one-pot Ugi four-component solvent-free conditions, followed 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. Preliminary bioassays indicated that compound 6b showed 44% and 42% mortality rate against Heliothis armigera and Pieris rapae at a concentration of 100 mg/L.
