Fungicidal activity ofN-(2-cyano-2-methoximinoacetyl)methionine and its derivatives and analogues
摘要:
AbstractThirty compounds comprising derivatives and analogues of N‐(2‐cyano‐2‐methoximinoacetyl)methionine were synthesised and tested for anti‐fungal activity against grape downy mildew, caused by Plasmopara viticola (de Bary) Berl. & de Toni, and rape downy mildew, Peronospora parasitica Fr. The most fungicidal compounds were the tert‐butyl ester of the substituted methionine and its oxidation products, the sulfoxide and sulfone, and the methioninol derivative and its oxidation products. Some of these compounds were up to ten times more active, especially against the grape downy mildew, than the commercial fungicide cymoxanil. The tert‐butyl esters of the methionine derivatives were consistently much more active than isomeric butyl esters, lower alkyl esters, free acids and S‐methylcysteine analogues of the active compounds, and possible reasons for these structure/activity correlations are discussed.
