Synthesis of(2E,4E)-3,7,11-trimethyl-2,4-dodecadienoic acid |

| Abstract: | The(2E,4E)-3, 7, 11-trimethyl-2, 4-dodecadienoic acid, a main intermediate of hydroprene and kinoprene—the insect growth regulator with jurenile hormone activity was synthesized in high stereochemical purity and excellent overall yield by condensation of tetrohydrocitral and ethyl 3-methylgluta-couate, decarboxy lation and isomerization. It was finally isolated through the formation of the insoluble ammonium salts. The unavailable isomer can e recycled. |
