Accelerating green heterocyclic synthesis: Convergence of AI, automation, and sustainable chemistry
Bulletin of the Korean Chemical Society, EarlyView.Green heterocyclic synthesis and data‐driven tools such as AI, high‐throughput experimentation, continuous flow, and self‐driving laboratories have developed largely in parallel. This review connects them and asks how green metrics such as E‐factor and PMI might serve as explicit optimization targets rather than post‐hoc measures, toward sustainable ...
