✦ Synopsis

Abstract

The title compounds 1 and 16 were synthesized by condensation of the dianions of β‐keto esters 5 and 11 with aldehydes 4, and lithium dialkylcuprate addition to the enol acetate or enol phosphate of unsaturated β‐keto esters 8 and 15. The (2__E__,4__E__)‐dodecadienoate derivatives 1 and 16 were formed in a stereoselective manner.
