Heterocycle-Substituted α-Methylene-γ-Butyrolactone Derivatives: Design, Synthesis, and Bioactivity against Phytopathogenic Fungi and Bacteria.
A series of 37 heterocycle-substituted α-methylene-γ-butyrolactone derivatives were designed and synthesized and exhibited the strongest antioomycete activity against P. capsici and Pseudomonas syringae pv actinidiae.
