AN EFFICIENT SYNTHESIS OF 1,3(E),5(Z), 1,3(E),5(E) AND 1,3(Z),5(Z)-TRIENES - APPLICATION TO THE SYNTHESIS OF GALBANOLENES AND (9Z,11E)-9,11,13-TETRADECATRIEN-1-YL ACETATE
M. Alami et al., AN EFFICIENT SYNTHESIS OF 1,3(E),5(Z), 1,3(E),5(E) AND 1,3(Z),5(Z)-TRIENES - APPLICATION TO THE SYNTHESIS OF GALBANOLENES AND (9Z,11E)-9,11,13-TETRADECATRIEN-1-YL ACETATE, Tetrahedron, 51(4), 1995, pp. 1209-1220
The (PdCu)-catalyzed reactions of trimethylsilyl acetylene with (E) or
(Z)-chloroenymes, or 1-chloro-(1E,3E)-dienes, followed by desilylatio
n and zinc-reduction of the triple bonds led respectively to (3E,5Z),
(3Z,5Z) and (3E,SE)-trienes. Application to the syntheses of galbanole
nes and (9Z,11E)-9,11,13-tetradecatrien-1-yl acetate has been realized
.
