N-芳(烷)磺酰基-N′-[1-氰(环)烷基]脲的合成与杀菌活性

SYNTHESIS OF SOME NOVEL N ARYL(ALKYL) SULFONYL N′ [1 NITRILE (CYCLO)ALKYL] UREAS AND THEIR FUNGICIDAL ACTIVITY

磺酰脲类化合物是已知的超高效除草剂［１］，而取代的氨基乙腈类化合物又具有多种生物活性如杀菌和除草活性［２～５］。为了寻找新的具有生物活性的先导化合物，作者以取代的氨基乙腈基团替代已知磺酰脲结构中的嘧啶胺或三嗪胺，合成了如下通式（１）所示的１３个未见文...

Thirteen novel N Aryl(alkyl)sulfonyl N′ [1 nitrile(cyclo)alkyl]ureas have been synthesized.Their structures were confirmed by IR,MS, 1HNMR and elementary analysis.All of them have some fungicidal activity against Sclerotinia sclerotiorum,etc.at 50mg/L in vitro.
