Sulfonylurea derivatives of formula:
wherein:
J is a phenyl group substituted by a heterocyclic methyl or heterocyclic ethyl group, or a benzyl group substituted by a heterocyclic group;
R is H or CH3, and
A is a mono- or bicyclic heterocyclic residue, e.g. pyrimidinyl or triazinyl, and their agriculturally suitable salts, exhibit herbicidal activity. Some also show a plant growth regulant effect. The novel compounds may be formulated for agricultural use in conventional manner. They may be made by a variety of synthetic routes, e.g. by reacting a sulfonamide JSOzNH2 with the methyl or phenyl ester of the appropriate pyrimidine or triazinecarbamic acid.
式中的磺酰脲衍生物:
其中
J 是被杂环甲基或杂环乙基取代的苯基,或被杂环基取代的苄基;
R 是 H 或 CH3,以及
A 是单环或双环杂环残基,如嘧啶基或三嗪基,以及它们在农业上适用的盐类,具有除草活性。有些化合物还具有植物生长调节作用。新型化合物可按常规方法配制成农用制剂。它们可以通过多种合成途径制得,例如,将磺酰胺 JSOzNH2 与适当的嘧啶或三嗪氨基甲酸的甲基或苯基酯反应。
