Description

Yejin Koo, Dongwoo Lee, Jiyong Park, and Sungwoo Hong report a light-driven copper method to build azetidines, small four-membered rings prized in drug design. Their 2026 paper uses strained bicyclic starting materials whose stored strain powers ring formation. Past routes to richly decorated azetidines of this kind were limited.

Their four-component reaction joins dienes, amines, and other partners in one step under visible light. A copper and light-harvesting pair work together to form the ring and a new carbon-nitrogen bond. The method tolerates many varied partners and favors one product layout strongly. Tests on complex, biology-linked molecules and a scaled-up run show practical reach. Computer work traces the selectivity to weak attractions that steer the bond formation.
