Front Cover: Stereoselective Control of Iminium Catalysis at Elevated Temperatures (Adv. Synth. Catal. 1/2026)

Iminium Catalysis The cover illustrates a well-known episode from “Journey to the West”. This narrative closely aligns with the central theme of the Research Article by Chunyu Wang and Sulei Zhang (10.1002/adsc.70214). Specifically, the “yin” and “yang” elements within the furnace serve as a metaphor for the complementary roles of amine catalysts and strong acids in the iminium catalytic system. The furnace’s tilted orientation reflects a deliberate deviation from the conventional 1:1 molar ratio of amine to strong acid commonly employed in previous studies. Significantly, Sun Wukong’s refinement under extreme thermal conditions parallels the robust thermal stability of our secondary amine–strong acid catalytic system, which maintains excellent stereoselective control at elevated temperatures and thereby delivers enhanced catalytic performance.
