Stille coupling reactions in the preparation of substituted trienic systems

The formation of the tetraenoate 2 was envisaged during a synthetic approach to the decalin system 1. The iododiene 3 was obtained in high yield from the corresponding stannyl derivative. The right hand fragment 13a was synthesized from propionate 8 using, during this sequence, a condensation of (E)-1-lithio-2-tributylstannylethene with aldehyde 10. The Pd(0)-catalyzed Stille coupling reaction between 3 and 13a was then realized in 75% yield to deliver the expected triene 23 which was then transformed into the expected tetraenoate 2.
