5-(azolyloxyphenylcarbamoyl)barbituric acid derivatives as anthelmintics

摘要

The invention relates to novel 5-(azolyloxyphenylcarbamoyl) barbituric acid derivatives of the general formula I ##STR1## wherein X is oxygen or sulfur;PPR.sub.1 is C.sub.1 -C.sub.6 alkyl, C.sub.1 -C. sub.6 alkoxy, C.sub.3 -C.sub.6 cycloalkyl or allyl;P PR. sub.2 is C.sub.1 -C.sub.6 alkyl or allyl;PPR. sub.3 is an unsubstituted or substituted five-membered azole ring which is bound through carbon and is selected from the group consisting of benzimadazole, benzoxazole, benzothiazole, imidazole, oxazole, thiazole, oxadiazole, thiadiazole and triazole; andPPR.sub.4 and R. sub.5 are each independently of the other hydrogen, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 haloalkyl, C.sub.1 -C.sub.6 alkoxy or C.sub.1 -C. sub.6 haloalkoxy;PPand to the tautomers and salts thereof, as anthelmintic compounds. Together with suitable carriers and further assistants, these compounds may be used in particular for controlling helminths which are parasites of animals.
