- Synthesis, herbicidal activity, and structure-bioactivity relationship of pyridyl-containing 2-phenyliminothiazolidines
-
A series of novel 2-phenyliminothiazolidine derivatives were designed and synthesized. All title compounds were characterized by 1H NMR and, in some cases, by 13C NMR, IR, and HRMS. Their agricultural bioactivities were evaluated and some of these compounds exhibited efficient herbicidal activities against Echinochloa crusgalli, Sorghum vulgare, Digitaria sanguinalis, Eclipta prostrasta, Cucumis sativus, and Brassica campestris at 50∈μg/cm3. Analysis of the quantitative structure-activity relationship (QSAR) showed that the electronic parameter was the main factor to affect herbicidal activities.
