The use of metal reagents in stereo- and regioselective functionalizations of conjugated dienes

Conjugated dienes have been selectively functionalized via 1-acetoxy-4-chloro-2-alkenes and via 2-(phenylsulfonyl)-1,3-dienes.In both these approaches nucleophiles can be added to the 1- and 4-positions.It was shown that also non-stabilized carbon nucleophiles (from cuprates or copper(I)-catalyzed Grignard reactions) can be used.The utility of the functionalizations was demonstrated by the syntheses of a marine natural product and a butterfly pheromone.Finally, the 2-(phenyl-sulfonyl)-1,3-dienes show a dual electron demand in Diels-Alder reactions and give cycloadducts with both electron-rich and electron-deficient olefins.
