To discover novel molecules with unique mechanism against plant pathogenic oomycetes, sixteen new sulfonate derivatives of ethyl maltol (3a–p) were synthesized by structural modification of 2‐ethyl‐3‐hydroxy‐4H‐pyran‐4‐one, and their anti‐oomycete activity against a serious agricultural disease, Phytophthora capsici Leonian was determined in this study. Among all tested compounds, derivatives 3e,...
In order to discover highly active fungicides, sixteen novel sulfonate derivatives of Fenjuntong were synthesized by structural modification of 2′‐hydroxybutyrophenone, and their anti‐oomycete activity against Phytophthora capsici Leonian was determined in this study. Among all tested compounds, compound 3b displayed more significant anti‐oomycete activity than the precursor Fenjuntong against P. capsici...
