Design, Synthesis, and Fungicidal Activity of Novel α-Methylene-γ-Butyrolactone Derivatives Bearing Benzofuran-2-yl Moiety.
A series of 30 novel α-methylene-γ-butyrolactone (MBL) derivatives were designed and synthesized. Bioassays revealed that several compounds exhibited potent fungicidal activities against Valsa mali, Rhizoctonia solani, and Phytophthora capsici. A25 showed the highest activity against V. mali (EC50 = 0.70 mg/L). Against...
