The back cover picture shows the first LA‐catalyzed [3+2]IMCC of GDA‐epoxides with carbon‐carbon double bonds. This provides an efficient and general strategy for construction of bridged oxa‐[ n .2.1] skeletons. A novel SN‐like mechanism through a carbon‐carbon bond cleavage of epoxide ring has been proposed. The colorful fireworks in the picture imply the generation of skeletal diversity from the epoxide‐diene, and express a dedication to the 100th Anniversary of Nankai University as well. More details are discussed in the article by Wang et al . on page 695–699.
