Stereoselective Synthesis of Octadeacpolyenoic Esters as an Insecticide
Octadecapolyenoic acid derivatives such as (+/-)-t-butyl coriolate, α-eleostearic acid, t-butyl punicate, and t-butyl (9Z,11E)-13-hydroxy-9,11-octadien-15-ynoate were synthesized starting from oleic acid with high stereoselectivity and their insecticidal
STEREOSELECTIVE PREPARATION OF 1-CHLORO-(E,E)-1,3-DIENES. APPLICATION TO THE SYNTHESIS OF METHYL ELEOSTEARATE.
The nickel (or palladium) catalyzed reaction of alkenylalanes with (E)-dichloroethylene affords 1-chloro-(E,E)-1,3-dienes under mild conditions.The syntheses of methyl α-eleostearate which is reported to be a feeding deterrent for the boll weevil on cotto
