Fe-catalyzed synthesis of methyl-(2E,4Z)-deca-2,4-dienoate, a component of sex pheromones of Pityogenes chalcographus and Acanthoscelides obtectus

Abstract

Stereoselective synthesis of methyl-(2E,4Z)-deca-2,4-dienoate, a component of sex pheromones of Pityogenes chalcographus and Acanthoscelides obtectus, was performed on the basis of Fe-catalyzed cross-coupling of methyl-(2E,4Z)-5-chloropenta-2,4-dienoate with n-pentylmagnesium bromide.
