Significance
Two nickel-catalyzed three-component couplings are introduced in this article: the coupling between enals, alkynes, and alcohols and the coupling between enones, alkynes, and aldehydes. The latter proceeds with good regioselectivities directly furnishing allylated 1,3-dicarbonyls. With this method, the laborious preparation of unsymetrically substituted 1,3-diketones and stereodefined allylic electrophiles can be elegantly circumvented.
