Fifteen novel (3-chloro-5-(trifluoromethyl) pyridin-2-yloxy) phenyl containing Baylis-Hillman adduct derivatives were designed and synthesized. Evaluation of their biological activities showed that methyl 2-((3-(3-chloro-5-(trifluoromethyl) pyridin-2-yloxy) phenoxy)(phenyl) methyl) acrylate (2g) exhibited efficient broad-spectrum fungicidal activity, with 100% control of wheat powdery mildew and cucumber downy mildew and 98% control of cucumber ...
