Front Cover: A Versatile Route to 3,3‐Disubstituded Phthalides Via Arylogous Michael Addition Catalyzed by Organic Base (Adv. Synth. Catal. 20/2025)

Arylogous Michael Additions The cover art, designed by Enzo Eddebbarh and Julien Petrignet, depicts a chef in a laboratory coat preparing a tomato sauce to represent a Michael adduct by combining simple ingredients: an arylphthalide and a Michael acceptor. The simplicity of the transformation is emphasized by the mild reaction conditions: acetonitrile and a pinch of DBU. The ease with which the product is formed mirrors the effortless preparation of a chef’s sauce and demonstrates compatibility with a broad range of substrates and reflecting the gram-scale feasibility.
