There are described new compounds of formula ##STR1## in which E is selected from the group consisting of residues of formula ##STR2## in which R" is selected from the group consisting of amino, vinyl, allyl, ethynyl, C.sub.1 -C.sub.5 alkyl, C.sub.1 -C.sub.5 alkoxy, or C.sub.1 -C.sub.5 alkylthio or a C.sub.1 -C.sub.5 alkyl group susbstituted by at least one halogen atom; and hydrogen; in which R.sup.1 and R.sup.2 are each selected from the group consisting of hydrogen, halogen, methyl and ethyl; and R' is selected from substituted phenyl when R" is other than hydrogen, and phenyl, thienyl and substituted phenyl and thienyl when R" is hydrogen. The compounds are useful in the control of parasites. Certain of the compounds have antimicrobial properties.
描述了新的化合物,其化学式为##STR1## 其中E是从以下基团中选取的:##STR2## 其中R"是从氨基,乙烯基,丙烯基,乙炔基,C.sub.1 -C.sub.5烷基,C.sub.1 -C.sub.5烷氧基或C.sub.1 -C.sub.5烷基硫基或被至少一个卤素原子取代的C.sub.1 -C.sub.5烷基;或氢;其中R.sup.1和R.sup.2各自选自氢,卤素,甲基和乙基;R'是选自取代苯基(当R"不是氢时),苯基,噻吩基和取代苯基和噻吩基(当R"是氢时)的基团。这些化合物对控制寄生虫有用。其中某些化合物具有抗微生物特性。
