The invention relates to new benzazole derivatives of the formula I
wherein X is oxygen or sulphur, R₁ is lower alkyl, lower alkenyl or cycloalkyl, optionally substituted, R₂ and R₃ independently of one another are each hydrogen, lower alkyl or cycloalkyl radicals or taken together are a substituted or unsubstituted bivalent hydrocarbon residue of aliphatic character in which the carbon atoms of the chain may be interrupted by a heteroatom, R₄ is either a group
wherein R₅ and R₆ independently of one another are each hydrogen, lower alkyl or cycloalkyl radicals, optionally substituted, or taken together R₅ and R₆ are a substituted or unsubstituted bivalent hydrocarbon residue of aliphatic character in which the carbon atoms of the chain may be interrupted by a heteroatom, or, R₄ is a group
where R₇ is a lower alkyl group, and their salts and N-oxides. The products are useful as anthelmintic effective agents. The products can be prepared to methods known per se.
本发明涉及式 I 的新苯甲唑衍生物
其中 X 是氧或硫,R₁ 是可选取代的低级烷基、低级烯基或环烷基,R₂ 和 R₃ 相互独立地各自是氢、低级烷基或环烷基,或者合在一起是取代或未取代的二价脂族性质的烃残基,其中链的碳原子可被杂原子打断,R₄ 是基团,R₅ 和 R₆ 相互独立地各自是氢、低级烷基或环烷基,或者合在一起是取代或未取代的二价脂族性质的烃残基,其中链的碳原子可被杂原子打断。
其中 R₅ 和 R₆ 各自独立地为氢、低级烷基或环烷基,可选择被取代,或 R₅ 和 R₆ 合在一起为脂肪族性质的取代或未取代的二价烃残基,其中链的碳原子可被杂原子打断,或者,R₄ 是一个基团。
其中 R₇ 是低级烷基,以及它们的盐和 N-氧化物。这些产品可作为有效的抗蠕虫剂。这些产品可以按照本身已知的方法制备。
