Abstract
The present invention relates to novel 23-imino derivatives of C-076 wherein the C-076 compounds are not substituted at the 13-position. The C-076 compounds (collectively) are isolates from the fermentation broth of Streptomyces avermitilis. The precursor 23-oxo compounds are prepared by selectively oxidizing suitably protected 13-deoxy C-076 aglycone compounds by using oxidizing agents. Subsequently, the 23-oxo compounds are converted to the 23-imino compounds. These novel compounds have potent anthelmintic, insecticidal, ectoparasticidal, nematicidal and acaricidal activity. Compositions containing these 23-oxo and 23-imino derivatives of 13-deoxy C-076 aglycones also are described herein.
