Abstract
Coupling of 9Z-iodo-1-(2-tetrahydropyranyloxy)-8-non-ene (6) and 1Z-propenylzinc (9) in the presence of Pd(PPH3)4 gave 1-(2-tetrahydropyranyloxy)-8Z,10Z-dodecadiene (10) in 90% yield. Deprotection, crystallisation and acetylation then gave a yield of 65% (from 4) of the title compound which was > 99% pure.
