Spinosyn derivatives as insecticides
Compositions including derivatives of spinosyns and methods for the production of derivatives of spinosyns are provided. The spinosyn derivatives described herein include spinosyn derivatives functionalized on the C5-C6 double bond of the spinosyn. The method produces spinosyn derivatives that exhibit activity towards insects, arachnids, and nematodes and are useful in the agricultural and animal health markets.
