The invention relates to new benzazole derivatives of the formula I ##STR1## wherein X is oxygen or sulphur, R.sub.1 is lower alkyl, lower alkenyl or cycloalkyl, R.sub.2 and R.sub.3 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, R.sub.4 is either a group ##STR2## wherein R.sub.5 and R.sub.6 independently of one another are lower alkyl or cycloalkyl radicals, optionally substituted, or taken together R.sub.5 and R.sub.6 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, R.sub.4 is a group ##STR3## where R.sub.7 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.
该发明涉及公式I的新苯并唑衍生物
其中X是氧或硫,R.sub.1是较低的烷基,较低的烯基或环烷基,R.sub.2和R.sub.3彼此独立地是氢,较低的烷基或环烷基基团,或者一起是取代或未取代的脂肪性碳氢残基,其链中的碳原子可能被杂原子中断,R.sub.4是一个群
其中R.sub.5和R.sub.6彼此独立地是较低的烷基或环烷基基团,可选择地取代,或者一起R.sub.5和R.sub.6是取代或未取代的脂肪性碳氢残基,其链中的碳原子可能被杂原子中断,或者,R.sub.4是一个群
其中R.sub.7是一个较低的烷基基团,以及它们的盐和N-氧化物。这些产品可用作抗蠕虫有效剂。这些产品可以按照已知的方法制备。
