Description
本发明涉及防治植物病原真菌的新型组合物,制备该组合物的新型活性物质以及该活性物质的制备方法。
本发明的特征之一是提供包括式(Ⅰ)化合物的杀真菌组合物
式中
Ar为苯基,未取代的或1-5碳烷基、1-5碳烷氧基、1-5碳烷基-SOn(n=0、1或2)、卤原子、NO2、CF3、CN、CH3OCH2、(CH3)2NCH2、COO烷基、CONH2或苯基的一至三取代物,1-或2-萘基,还可为由氯取代的2-,3-或4-吡啶基;或嘧啶基或喹啉基;

R4为CN或CONH2;
R5为H原子或-CH3或-C2H5;
R6为H原子或-CH3;
X为O或S原子。
大多数式(Ⅰ)化合物为新化合物,因此本发明的又一特征是提供式(Ⅰ)化合物
其中
Ar为苯基,未取代的或1-5碳烷基、1-5碳烷氧基、1-5碳烷基-SOn(n=0、1或2)、囟原子、NO2、CF3、CN、CH3OCH2、(CH3)2NCH2、COO烷基、CONH2或苯基的一至三取代物,1-或2-萘基,还可为由氯取代的2-,3-或4-吡啶基;或嘧啶基或喹啉基;
R1为H原子或1-5碳烷基或烯丙基;
R4为CN或CONH2;
R5为H原子或-CH3或-C2H5;
R6为H原子或-CH3;
X为O或S原子。
还可为外消旋体或光学异构体的混合物或纯的对映体或非对映体,条件是:
(a)当Q为-CH(CH3)和CR2R3R4为-CH2CN时,
芳基-X-不代表
(b)当(1)R1为H原子或1-4碳烷基,
(2)R2为H原子或甲基或乙基,
R3为H原子或甲基,乙基,苯基或苄基;或
R2和R3一起代表(CH2)4或(CH2)5基,

(d)当芳基为下面三式之一时,
-X-Q-CONR1-CR2R3R4不代表-O-CH2-CONH-CH2CN。
式(Ⅰ)化合物可含非对称碳原子,因而本发明还包括这些化合物的各对映体及其混合物。
若取代物R1-R6含有烃链,则这些烃链可以相同或不相同,可为直链,也可为支链,达4碳特别是3碳的链是优先选择的烃链。芳基中优先选择的取代烷基为甲基。鹵原子包括F,Cl,Br和I,优先选择的为Cl或F。芳基中的取代基可以相同或不相同,虽然其中一般只带一个CF3,CN,NO2,(CH3)2NCH2,1-5碳烷基-SOn和苯基。如芳基为喹啉基,则优先选择的为8-喹啉基。
可用几个方法制备式(Ⅰ)化合物,这些过程形成了本发明的又一特征。所用方法包括:
(a)式(Ⅱ)化合物与式(Ⅲ)化合物进行反应,消除HY;
Ar-X-Q-COY (Ⅱ)
(其中Ar,X和Q定义同前,Y为离去基团如鹵原子(优先选择的为
Cl原子),或烷氧基,羟基或酰基)
(其中R1-R4定义同前)
(b)式(Ⅳ)化合物与式(Ⅴ)化合物反应
Ar-X-M (Ⅳ)
(其中Ar和X定义同前,M为H原子或碱金属阳离子)
(Ⅴ)
(其中R1-R4和Q定义同前,Z为囟原子或芳基磺酰氧基)。
第1类型的反应最好是在惰性溶剂如二氯甲烷、甲苯、乙腈、乙醚或其混合物中于室温至反应混合物沸点的温度范围内进行,反应可用HY结合剂促进。如HY为酸(例如HCl)则用碱;如HY为水则用二环己基碳化二亚胺或羰基二咪唑。
式(Ⅱ)的起始物料为已知化合物,或者可用常规方法制得。如Y=OH时,可将苯酚或苯硫酚(Ar-XH)与一适合的溴代羧酸酯在碱存在下反应,然后进行酯的水解而制得。用这样制得的羧酸可形成相应的式(Ⅱ)的酰氯(如与亚硫酰基(二)氯反应)。
α-氨基腈[R4=CN的式(Ⅱ)化合物]可从相应的酮或醛、Na CN和NH4Cl于水中用斯特克尔(Strecker)合成法制得[cf.Houben-Weyl,Vol.Ⅷ,p.274ff(1952)]。α-氨基酰胺[R4=CONH的式(Ⅲ)化合物]可用相应的腈经部分水解制得。
第2类型反应可在惰性极性溶剂中进行,若M=H,可加入碱,形成M=K或Na的式(Ⅳ)化合物的条件是优先选择的条件。
优先选择的溶剂为乙腈时,式(Ⅴ)中优先选择的Z为Br原子或CH3-C6H4-SO3-。反应一般在高温(如回流温度)下进行。适合的碱包括如碱金属碳酸盐和碱金属氢氧化物,也可用足够的碱性胺(如三乙胺)。
根据R2-R6的定义的不同,式(Ⅰ)化合物可出现1-2个不对称中心。需要时,可用常规方法将异构体分开,或直接用光学活性起始产物进行合成。
现将用有光学活性的α-羟基酸酯制备式(Ⅱ)的光学活性化合物的两种方法说明如下(不对称碳原子用*标出):
(Ⅱ),(-)-式 (Ⅱ),(+)-式
“烷基”最好为甲基或乙基。
式(Ⅱ)的其它化合物可按相同的步骤制得。
式(Ⅴ)的旋光起始原料可用相同的步骤制得;在这种情况下,也可制得式(Ⅴ)的其它光学活性化合物。
式(Ⅰ)化合物对植物病原真菌具有杀灭作用,因此本发明的又一对特征是预防和/或抑制植物的霉菌感染,特别是防治水稻的霉菌病害(如梨孢霉菌属-Piricularia-病)。
尽管这些新化合物是部分衍生自除草剂(Dichlorprop,2,4-DB),但出人意料的是植物对这些化合物具有很好的耐药力。
本发明的杀菌组合物可用常规赋形剂和/或载体与式(Ⅰ)化合物一起而制成常见的制剂,并可用适量水稀释成喷洒液备用。常见剂型包括乳油,可湿性粉剂,撒粉和粒剂等,其中活性物质含量可高达80%(重量)。
本发明的化合物的活性(例如抗梨孢霉菌的活性)是在热带条件下用水稻进行试验的。在以梨孢霉菌自然感染的稻种中选取2排(Ⅰ和Ⅱ)播种水稻种子,于播种后第41、45和49天用特定浓度的喷洒液处理,而对比稻种仅用水处理,并于最后一次喷洒后6、8、10和13天评定结果(以植物感染%表示)。
本发明化合物对防治梨孢霉菌被证明是非常有效的,植物的抗药性也好。
其它试验如下:
抗水稻梨孢霉菌的效果试验
A.叶片处理
用含有1000、500或250ppm所试活性物质的乳剂或悬浮液喷洒生长在栽培箱内的水稻植株,直至有液滴滴下。处理后2天,将栽培箱置于室外的感染水稻植株之间5-6天,使其产生感染。其后5-8天,对其作用进行评定。
B.土壤处理
将含有500ppm特定活性物质的乳剂或悬浮剂倾到生长在花盆中的水稻植株的根部。处理后两天,将花盆置于室外以梨孢霉菌感染的水稻植株之间,使其产生感染,感染后5-7天评定其结果。
评定结果按1-3分级:
1:无感染
2:轻微感染
3:感染程度与未处理的对照植株相似
表A中的数是3次试验和在不同时间所定级数的平均数。
C.水下应用(湿润应用)
将水稻植株种于盛有土壤的桶中,加水直至在土壤上部形成水的覆盖层,以乳液或悬浮液加入活性物质,其量相当于每公顷施用8公斤或4公斤或2公斤的活性组分。处理后2天,将受试植株置于室外被感染的水稻植株之间,并在整个实验过程中让其感染。在未处理的对照植株受感染后1天评定其结果,评定需进行4-5次(每一活性物质做3个实验),方法如A和B中所述。表中的数是三个实验在实验进行的不同时间所定的几个级的平均值。
