Front Cover Picture: Gold‐Catalyzed Synthesis of Ortho‐Quinone Methide Analogues as Reactive Synthetic Precursors (Adv. Synth. Catal. 10/2024)

The front cover illustrates pandas as gold catalysts on trees, with the leaves symbolizing reaction reagents, intermediates, and products. It portrays the 5‐exo‐dig‐selective cyclization of α,β‐ynones. The smiling panda under the tree captures the synthesized 2‐exomethylene indolin‐3‐ones, which reflect the isolation of the intermediates. The illustration suggests the synthetic utility of the 2‐exomethylene indolin‐3‐ones for syntheses of spiropseudoindoxyl and pyranoindole derivatives, and implies the opening of avenues toward the discovery of new bioactive materials.
