The (Pd-Cu)-catalyzed reactions of trimethylsilyl acetylene with (E) or (Z)-chloroenynes, or 1-chloro-(1E,3E)-dienes, followed by desilylation and zinc-reduction of the triple bonds led respectively to (3E,5Z), (3Z,5Z) and (3E,5E)-trienes. Application to the syntheses of galbanolenes and (9Z,11E)-9,11,13-tetradecatrien-1-yl acetate has been realized.
三甲基甲硅烷基乙炔与(E)或(Z)-氯乙炔或1-氯-(1E,3E)-二烯的(Pd-Cu)催化反应,然后对三键进行甲硅烷基化和锌还原(3E,5Z),(3Z,5Z)和(3E,5E)三烯。已经实现了其在加拉班油烯和乙酸(9Z,11E)-9,11,13-十四碳三烯-1-基酯的合成中的应用。
