Abstract
提供了一种制备具有杀菌活性的环戊烯衍生物、环戊烷衍生物及环己烷衍生物的方法。这些衍生物的结构式及各基团的定义详见说明书。
Description
本发明涉及制备明显具有杀菌活性的环戊烯衍生物和某些环戊烷及环己烷衍生物的方法,所有这些物质均可用于制备其它具有杀菌活性的环戊烷衍生物。
在Bull一文中(日本化学协会,43(7),1970,第2204-8页)公开了1-苄基-2-羧基环戊-1-烯,在Bull另一文中(日本化学协会,60(2),1987,笫836-8页)公开了1-苄基-2-甲氧基羰基环戊-1-烯。但是,这些参考文献未指出这两种化合物具有杀菌活性。
不仅如此,美国专利4067823公开了1-亚苄基-2-甲氧基羰基环戊烷,Liebigs一文(化学年鉴,(8),1980,第1283-95)公开了1-(4-甲氧基-亚苄基)-2-甲氧基羰基环戊烷。
相应地,共同未决专利申请T616公开了以下通式的具有杀菌性的化合物其中n代表0-5之间的一个整数;各R代表卤素原子,硝基,氰基,羟基,烷基,卤烷基,烷氧基,卤烷氧基,氨基,烷氨基,二烷氨基,烷氧羰基,羧基,烷酰基,烷硫基,烷亚磺酰基,烷磺酰基,氨基甲酰基,烷酰胺基,环烷基或苯基; R1和R2分别代表氢原子或烷基;R5代表氢原子或烷基或环烷基;条件是当n为0且R1和R2均代表氢原子时,R5不代表氢原子或甲基。
T616介绍的用市售原料制备式Ⅰ化合物的方法需要至少5个合成步骤。由于每个步骤得到的产率不为100%,所以式Ⅰ化合物的可能的产率随各连续的合成步骤而减少。但是,现在尚未发现用少于两个合成步骤提供式Ⅰ化合物高的产率的新方法来制备这类化合物。
所以,本发明提供了一种制备上述式Ⅰ化合物的方法,该方法包括在一种极性溶剂存在下,加热通式(Ⅱ)的化合物,或通式(Ⅲ)的化合物,(其中n,R,R1,R2和R5定义如上,X和Y分别代表卤素、最好是氯或溴原子)与通式(Ⅳ)的化合物
MOR5 (Ⅳ)其中R5定义如上,M代表碱金属、最好是钠原子。
所说的极性溶剂最好是通式(Ⅴ)的化合物
R5OH (Ⅴ)(其中R5定义如上),二甲基甲酰胺或二甲亚砜。
若式Ⅴ化合物用作溶剂,R5最好具有式Ⅳ和式Ⅴ中同样定义。例如,若式Ⅳ化合物是甲醇钠,推荐式Ⅴ的溶剂是甲醇。
反应最好在80℃-溶剂的回流温度下进行。最好,用过量的式Ⅳ化合物。
当任何取代基R,R1,R2和R5代表或含有一种烷基取代基时,这种取代基可以是直链或支化的,可含有12个以下的碳原子,最好是6个以下、特别是4个以下。环烷基取代基可含有3-8个、最好3-6个碳原子。
推荐R1和R2分别代表氢原子或C1-4烷基,特别是甲基。
R最好是卤素,特别是氯原子。
推荐R5代表氢原子或C1-6烷基。
特别推荐的是,n是1,R代表氯原子、最好取代在苯环的4-位上,R1和R2均代表氢原子或均代表甲基;R5代表甲基。本发明提供了一种通式(Ⅱ)的化合物,其中n代表0-5之间的一个整数;各R代表卤素原子,硝基,氰基,羟基,烷基,卤烷基,烷氧基,卤烷氧基,氨基,烷氨基,二烷氨基,烷氧羰基,羧基,烷酰基,烷硫基,烷亚磺酰基,烷磺酰基,氨基甲酰基,烷酰胺基,环烷基或苯基;R1和R2分别代表氢原子或烷基;R5代表氢原子或烷基或环烷基;条件是当R1和R2均为氢原子且R5代表甲基时,n不为0且R不代表甲氧基(n为1时)。
当任何上述取代基代表或含有烷基取代基时,这种取代基可以是直链或支化的,且可含有12个以下、最好是6个以下、特别是4个以下的碳原子。环烷基取代基可含有3-8个、最好是3-6个碳原子。
推荐R1和R2分别代表氢原子或C1-4烷基,特别是甲基。
R最好是卤素,特别是氯原子。
R5也最好代表氢原子或C1-6烷基。
特别推荐的式Ⅱ化合物族中,n是1,R代表氯原子、最好取代在苯环的4-位上,R1和R2均代表氢原子或均代表甲基;R5代表甲基。
本发明还提供了一种制备上述式Ⅱ化合物的方法,该方法包括在通式(Ⅴ)的溶剂存在下,
ROR5 (Ⅳ)其中R5定义如上且M代表碱金属、最好是钠原子。
最好,R5具有式Ⅳ和式Ⅴ中的同样定义。例如,若式Ⅳ化合物是甲醇钠,则式Ⅴ的溶剂最好是甲醇。
反应在0℃-室温并采用稍过量的式Ⅳ化合物进行比较有利。
本发明的另一方面是提供通式(Ⅲ)的化合物:其中n代表0-5之间的一个整数;各R代表卤素原子,硝基,氰基,羟基,烷基,卤烷基,烷氧基,卤烷氧基,氨基,烷氨基,二烷氨基,烷氧羰基,羧基,烷酰基,烷硫基,烷亚磺酰基,烷磺酰基,氨基甲酰基,烷酰胺基,环烷基或苯基;R1和R2分别代表氢原子或烷基;X和Y分别代表卤原子。
当任何上述取代基代表或含有烷基取代基时,这种取代基可以是直链或支化的且可含有12个以下、最好是6个以下、特别是4个以下的碳原子。环烷基取代基可含有3-8个、最好3-6个碳原子。
推荐R1和R2分别代表氢原子或C1-4烷基,特别是甲基。
最好,R代表卤素,特别是氯原子。
