The Front Cover shows a figurative representation of the cyclization of internal ϵ ‐acetylenic β‐ketoesters as bending horseshoes into rings. The transformation requires not only the use of a gold catalyst (golden gloves), but also the application of a high pressure, generated by the burly blacksmith. In contrast, the frail apprentice delivers only ambient pressure to the system, which is insufficient for effective cyclization despite the use of golden gloves. In their Full Paper, W. Chaładaj et al. demonstrate the impact of pressure on the Au‐catalyzed Conia‐ene reaction of internal ϵ‐acetylenic β‐ketoesters. More information can be found in the Full Paper by W. Chaładaj et al. on page 4334 in Issue 23, 2017 (DOI: 10.1002/cctc.201701388).
