The construction of skipped diene is a vital research area for organic synthesis, whose structure is found in many bioactive molecules. The synthesis of skipped diene from simple and readily available starting materials is highly desirable. Herein a nickel-catalyzed multicomponent coupling of 1,3-butadiene, aldehydes, alkynes, and Schwartz reagents for the preparation of skipped dienes is described. The reagents are common feedstock chemicals, especially 1,3-butadiene is an abundant feedstock produced from petroleum cracking. Moreover, the hydrozirconation of alkynes using Schwartz reagent was applied to in-situ prepared the alkenylzirconium reagents, which were used directly without further treatment. Various (E,E)-1,4-diene products were synthesized with excellent regio- and stereo-selectivity. The mild and straightforward reaction condition enables a broad substrate scope and good functional group tolerance. This protocol provides a useful and practical synthesis of skipped dienes.

Key words: skipped diene, nickel catalysis, butadiene, multicomponent reaction, coupling
