Dienes as Versatile Substrates for Transition Metal-Catalyzed Reactions.

Dienes have been of great interest to synthetic chemists as valuable substrates due to their abundance and ease of synthesis. Their unique stereoelectronic properties enable broad reactivity with a wide range of transition metals to construct molecular complexity facilitating synthesis of biologically active compounds. In addition, structural diene variation can result in substrate-controlled reactions, providing valuable mechanistic insights into reactivity and selectivity patterns. The last decade has seen a wealth of new methodologies involving diene substrates through the power of transition metal catalysis. This review summarizes recent advances and remaining opportunities for transition metal-catalyzed transformations involving dienes.
