Description
技术领域
本发明涉及3-酰基吡咯烷-2,4-二酮类化合物及除草活性。
背景技术
对羟基苯基丙酮酸双氧化酶(4-hydroxyphenylpyruvate dioxygenase,HPPD)存在于各种生物体中并被提取出来,它是一种铁-酪氨酸蛋白,在植物体内可将对羟基丙酮酸催化转化为尿黑酸,进而转化为光合作用中电子传递所需要的重要物质质体醌和生育酚,其中质体醌还是影响八氢番茄红素去饱和酶催化的关键辅助因素,鉴于其上述重要作用和特点同时,由于该酶的抑制剂2-(2-硝基-4-三氟甲基苯甲酰基-1,3-二酮已经应用于临床上治疗酪氨酸病,对人体无不良作用,使之成为继ALS、ACC以及Protox之后的又一新的除草剂靶标酶和临床上治疗酪氨酸病靶标酶,自1982年捷利康公司发现高效三酮类玉米田苗后防除阔叶杂草除草剂磺草酮(sulcotrione)后,该领域受到各大农药方面专家的重视,该类化合物的研究获得了极大的发展,许多类似的商品化品种得到应用。
1994年世界专利WO1994/01401报道了含3-苯甲酰基吡咯啉-2,4-二酮类化合物及生物活性。(结构如下:)
X,Y,Zn为氢,卤素,烷基磺酰基,烷基,烷氧基
F,G,J,K=氢,烷基
成功地将吡咯杂环代替了常见的六元环,所得到的化合物具有较好的除草活性,而且对作物表现出优良的选择性。对玉米生长安全。它在1000克/公顷剂量下,可作为玉米田中cyperus,digitaria,amaranthus,galiusoga和stellaria等杂草的除草剂。
上述文献虽然记载了3-酰基吡咯烷-2,4-二酮类化合物,但是却没有任何具体地记载本专利中所提及的3-酰基吡咯烷-2,4-二酮类化合物,更没有任何具体地记载这些化合物的除草活性。
发明内容
本发明的目的是提供一种3-酰基吡咯烷-2,4-二酮类化合物及其制备方法和应用。本发明的化合物对禾本科杂草有很高的除草活性,而且对作物表现出优良的选择性,对玉米生长安全。
本发明是下述通式(I)化合物:
其中,
R1:CH3、CH(CH3)2、-CH(CH3)CH2CH3、t-Bu、-CH2C6H5。;
R2:H、CH3;
R3:任选取代的苯基、萘基、苯氧苯基;
任选的取代基为C1~C6烷基、C1~C6烷氧基,取代基数量为1~5。
本发明用烷氧基取代芳环上的氯原子后,所得的3-酰基吡咯烷-2,4-二酮的除草活性和对作物的选择性都有了较大的提高,尤其在对作物的选择性上表现更为突出。本发明的化合物在187.5克/公顷剂量下对稗草、马唐有很高的除草活性。

实施例6 除草活性的初筛测定
盆栽法(茎叶处理):在直径8cm的塑料小杯中放入一定量的土,加入一定量的水,播种后覆盖一定厚度的土壤,于花房中培养,幼苗出土前以塑料覆盖。出苗后,每天加以定量的清水以保持正常生长。当幼苗长到一定时期进行茎叶喷雾处理。处理剂量为1500g/公顷。处理21天后调查结果,测定地上部鲜重,以鲜重抑制百分数来表示药效。
