  A Stereoselective Approach to γ-Functionalized Carbonyls Exploiting the Cu-Promoted S_N2′ Reaction

  摘要：

  While several efficient processes exist to effect the stereoselective creation of carbon-carbon bonds in the alpha- and beta-position of carbonyls, functionalization of the gamma-position is much more challenging. We disclose an alternative methodology exploiting the Cu-promoted S(N)2' reaction to achieve the addition of various nucleophiles upon the allylic lactones 5a-d which lead to the generation of the desired y-functionalized alpha,beta-unsaturated aldehydes 6 following in situ hydrolysis.
