Cu-Catalyzed Transformations of 1,3-Dienes: Use of Allyl Copper Intermediates in Functionalization

Cu-catalyzed transformations using 1,3-dienes as substrates are described. First, the basic concept of transformation including the generation of reactive allylcopper intermediates as well as a plausible catalytic cycle are briefly described. Second, the borylative transformations of 1,3-dienes including hydroboration, bora-acylation, boraformylation, bora-cyanation and the reactions with carbonyl compounds were described. Third, the silylative transformations of 1,3-dienes such as sila-acylation and silaformylation were introduced. In each section, the scope of substrates is briefly described.
