Front Cover Picture: Synthesis of Benzo[a]fluorene, Benzo[c]fluorene, and Benzo[j]fluoranthene via a Lewis Acid‐Catalyzed Prins‐Type Cycloaromatization: Application to the Total Synthesis of Viridistratin A (Adv. Synth. Catal. 3/2024)

The front cover illustrates the streamlined synthesis of representative non‐alternant polycyclic aromatic hydrocarbons through Lewis acid‐catalyzed Prins‐type cycloaromatization (on the earth). Notable features of the catalytic reaction encompass air tolerance, high productivity, remarkably short reaction times, and scalability. The plausible mechanism suggests that Prins‐type benzannulation competes with oxonium‐ene cyclization. The robustness and high productivity of the key reaction allowed the application towards total synthesis of natural benzo[j]fluoranthene, viridistratin A (on the moon).
