N-sulfonyl amino acid amides, a novel class of compounds with fungicidal activity [1]

Cederbaum, Fredrik,De Mesmaeker, Alain,Jeanguenat, Andre,Kempf, Hans-Joachim,Lamberth, Clemens,Schnyder, Anita,Zeller, Martin,Zeun, Ronald

, p. 680 - 684 (2003)

Novel types of oomycete fungicides have been designed and prepared. The synthetic approach to these N-sulfonyl amino acid amides is outlined. Bioassays demonstrate their high efficacy against important plant diseases like Phytophthora infestans (tomato and potato late blight) and Plasmopara viticola (grape downy mildew). Structure-activity relationship studies are discussed.
