抄録

Thirty-three 5-methoxy-2-nitrophenylphosphoramidothioates and phosphonamidothioates were synthesized and tested for their antifungal activity against downy mildew on cucumber in greenhouse pot tests. Among the compounds O-ethyl O-(5-methoxy-2-nitrophenyl) phosphoramidothioates having either an isopropylamino group, a 1-cyano-2-propylamino group, a 1-methoxy-2-butylamino group, or a s-butylamino group showed the highest activity. A 1-methoxy-2-propylamino group, a 3-methoxypropylamino group and a 1, 1-dioxotetrahydrothiophen-3-ylamino group effectively reduced the phytotoxicity without affecting the antifungal activity. Among N-isopropylphosphoramidothioates and phosphonamidothioates, O-methyl or O-ethyl phosphoramidothioates showed the highest activity. Chloromethylphosphonamidothioate was also effective, but phenylphosphonamidothioate was not effective. O-Ethyl O-(5-methoxy-2-nitrophenyl) N-s-butylphosphoramidate was hardly effective.
