    摘要: Novel avermectin derivatives of formula I are disclosed, wherein the 4''-hydroxy group is replaced by a substituted acylamino or benzoylamino group. These avermectin derivatives can be further derivatized at the 5- and 23-positions as ketoximes or O-substituted ketoximes. The 4''-substituted avermectin derivatives are prepared by the acylation of the known 4''-aminoavermectins with acylating reagents. The new compounds are potent anti-parasitic agents, in particular, the compounds are anthelmintic, insecticidal and acaricidal agents.

    摘要: There are disclosed novel avermectin derivatives wherein the outer oleandrose ring of avermectin or avermectin monosaccharide is homologated by addition of diazomethane to 4˝- or 4′-oxo-avermectin to afford the oleandrose 4˝- or 4′-spiro-epoxide. The homologated avermectins can then be further derivatized to afford additional novel avermectins. The new compounds are potent antiparasitic agents, in particular, the compounds are anthelmintic, insecticidal and acaricidal agents.

    摘要: There are disclosed novel avermectin reduction products. The compounds are prepared by selective catalytic hydrogenation of avermectin-like compounds or by reaction of selected double bonds with electrophylic reagents. The reduced avermectin compounds have utility as anti-parasitic agents and compositions for that use are also disclosed. The compounds are also highly potent insecticides against agricultural pests. The reduced, avermectin compounds have increased stability towards light which prolongs their insecticidal activities when applied to field crops subject to irradiation by sunlight.

    摘要: The natural stereochemistry at the 13-position of avermectin aglycones, normally α-oriented or below the plane of the molecule, is inverted or epimerized into the β-position. The procedure starts with the avermectin aglycone compounds where the 13α-hydroxy group is substituted with a leaving group. Treatment of the substituted compound with tetra alkyl ammonium nitrate displaces the leaving group, substitutes a nitrate ester or a nitrooxy group, for the hydroxy and inverts the 13-stereochemistry to β. Reduction of the nitrooxy group returns the 13-hydroxy group and retains the 13-β configuration. The intermediate 13-nitrooxy compounds are themselves potent anti-parasitic agents.
