Frame‐Shifted Synthesis of Oligoheterocycles as a Platform for Molecular Design

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Modern chemistry seeks to turn the simple raw materials into complex molecules that matter in health, agriculture, and technology. Among these, oligoheterocycles stand out for their versatility, yet they are most often built by cross‐coupling reactions that often rely on expensive metal catalysts.
