    摘要: Derivatives of C-076 compounds are described in which the C-076 molecule, a series of macrolides, has the 23-hydroxy group thereof oxidized to the 23-keto group. The 23-keto compounds are prepared by selectively oxidizing the suitably protected 23-hydroxy compound using such oxidizing agents as pyridinium dichromate, chromic acid-dimethyl pyrazole, chromic acid, chromic acid-acetic acid, and the like. Alternatively, selective oxidation of the unprotected 23-hydroxy compound may be accomplished by placing the compound in soil. Further reaction of the oxidized C-076 compounds is also possible. The compounds thus produced have profound anthelmintic, insecticidal, ectoparasiticidal, and acaricidal activity. Compositions containing the described C-076 derivatives as the active ingredient thereof are also disclosed.
