spinosyn J, 3′-Ethoxy-5,6-dihydro-
3'-Ethoxy-5,6-dihydrospinosyn J is the major component in the second generation spinosyn family of bio-insecticides marketed as Spinetoram. 3'-Ethoxy-5,6-dihydrospinosyn J is a semi-synthetic compound prepared by selective ethylation and hydrogenation of Spinosyn J, itself a fermentation product from a biosynthetically blocked mutant of Saccharopolyspora spinosa. As an insecticide, 3'-ethoxy-5,6-dihydrospinosyn J is considered more potent, and to have earlier onset and longer duration of action than combinations of spinosyn A and D.
