    • Novel avermectin derivatives are disclosed, wherein the 5-hydroxy group is replaced by an oxime group. The avermectin-5-oximes can further be derivatized at the 4"- or 4'-positions as amino, substituted amino, acylhydrazone, semicarbazone, or substituted semicarbazone analogues. The avermectin-5-oximes are prepared by the oxidation of the 5-hydroxy compounds with manganese dioxide or with pyridinium dichromate to the known 5-oxo analogues, and these are then reacted with a hydroxylamine salt. The new compounds are potent anti-parasitic agents, in particular, the compounds are anthelmintic, insecticidal and acaricidal agents.
    • 公开了新的阿维菌素衍生物,其中5-羟基被肟基替代。 阿维菌素-5-肟可以进一步在4“ - 或4'-位被衍生为氨基,取代的氨基,酰腙,缩氨基脲或取代的缩氨基脲类似物,阿维菌素-5-肟通过氧化5- 羟基化合物与二氧化锰或与重铬酸吡啶鎓转化成已知的5-氧代类似物,然后将它们与羟胺盐反应,新化合物是有效的抗寄生虫剂,特别是该化合物是驱虫剂,杀虫剂和杀螨剂。
