The front cover picture , provided by Xianxiu Xu and co‐workers, illustrates a double annulation of o ‐enoyl arylisocyanides with α,β‐unsaturated carbonyl compounds under metal‐free conditions, which allows the efficient construction of a wide range of acridones and their cyclo[b ]fused derivatives. This practical protocol features a one‐pot domino process involving an isocyanide‐based [1+4] cycloaddition, an aminofuran‐based intramolecular [4+2] cycloaddition, ring opening and aromatization. Details of this work can be found in the full paper on pages 2379–2384 (L.‐J. Zhang, W. Yang, Z. Hu, X.‐M. Zhang, X. Xu, Adv. Synth. Catal . 2020 , 362 , 2379–2384; DOI: 10.1002/adsc.201901560).
