本发明实施例1制得的目标化合物6a、7a和8a的结构式及分子式如表1所示,表1中的其余化合物,如6b~6h为通过与步骤(1)-(4)类似步骤合成的化合物,这些化合物与6a的不同之处在于取代基R不同,工艺上步骤(4)采用的酰氯种类不同。
表1取代3-(吡啶-2-基)苯氨基衍生物的化学结构
本发明化合物经试验证明其在防治阔叶杂草和部分禾本科杂草的应用中效果明显,且结构简单,制备工艺简单,生产成本低,应用前景广阔。
实施例2
本实施例进行取代3-(吡啶-2-基)苯氨基衍生物的除草活性试验,具体如下:
采用喷雾法对三种代表性的禾本科杂草黑麦草、稗草、马唐以及三种代表性的阔叶杂草苘麻、反枝苋和苜蓿进行苗后除草活性测试,用常见的具有广谱除草活性的PPO类除草剂三氟羧草醚作为对照。
将一定质量(0.01-5mg)的取代3-(吡啶-2-基)苯氨基衍生物溶于200μL N,N-二甲基甲酰胺中,加入到10mL容量瓶中,然后加入Tween-80(0.1%)作为乳化剂,并加水至10mL。喷雾剂量(活性成分,g ai/ha)计算方法是将喷雾抑制剂(即取代3-(吡啶-2-基)苯氨基衍生物)的质量除以花盆的上表面积。种植前选择直径8厘米的花盆,填入6~8cm深的土。试验杂草种子约6~10粒,播种深度1~3cm。实验期间,温度保持在25-28℃,空气湿度保持在约50-75%。苗后除草活性选取2-3叶期单子叶杂草和阔叶杂草用稀释的抑制剂乳剂处理。在处理后15~21天内对除草活性的结果进行目视评价,每个处理重复三次。
目标化合物对黑麦草、稗草、马唐、反枝苋、苘麻和苜蓿的苗后除草活性如表2所示。
表2取代3-(吡啶-2-基)苯氨基衍生物的苗后除草活性
由表2可知,除草活性测试结果表明,大部分化合物都有较好的除草活性,特别是对阔叶杂草有特效,其中化合物8d对阔叶杂草的除草活性优于对照药剂三氟羧草醚,甚至在75g ai/ha下对大部分杂草都有较好的除草活性,对阔叶杂草具有优异的除草活性,对黑麦草的除草活性较低。构效分析结果表明引入饱和烃和小基团有利于发挥除草活性,如甲基和异丁基等,而引入饱和烷烃对阔叶杂草能有显著的除草活性,化合物8d在37.5g ai/ha对供试阔叶杂草仍有显著的除草活性,但是对禾本科杂草防效明显降低。
实施例3
目标化合物的作物安全性测试
采用实施例2中使用的温室喷雾法,采用喷雾法在75-150g ai/ha的施药剂量下对水稻、小麦、玉米、棉花、花生、大豆六种作物进行了安全性评价,结果如表3所示。
表3取代3-(吡啶-2-基)苯氨基衍生物苗后作物选择性
由表3可知,当R为酰基、酰胺、硫代酰胺时,在75-150g ai/ha时对水稻、小麦、玉米、花生和大豆具有良好的选择性,其中R为酰胺时作物选择性明显优于三氟羧草醚。但是,当R为硫代酰胺时,化合8d的对大豆、棉花、花生的作物选择性明显降低,但其对棉花的选择性的仍优于三氟羧草醚,具体如图1所示,作物种类从左到右依次是:玉米、水稻、小麦、花生、棉花和大豆,化合物8d在施药剂量为150g ai/ha时对玉米、水稻、小麦几乎无伤害,对花生的损伤与三氟羧草醚相当,对棉花的损伤相比三氟羧草醚稍低,其中化合物8d对大豆的损伤相比三氟羧草醚稍高但对大豆却不会完全致死。
