Retrosynthetic analysis is a method chemists use to simplify complexity by breaking down target molecules into commercially available building blocks. Today, artificial intelligence is accelerating this process by learning from millions of known reactions; it can not only propose synthetic routes faster than humans but also automatically incorporate constraints such as safety and feasibility. Future developments will focus on building integrated systems that combine traditional tools with large language models (LLMs) to explore a broader chemical space and deliver robust, practical synthetic strategies.

Recommended practical workflow
Target molecule → AI tool(s) generate candidate routes → rank by step count / cost / toxicity / commercial availability → verify reaction conditions and literature precedent in SciFinder-n or Reaxys → check supplier databases → experimental validation.
AI-generated routes are predictions, not experimentally verified procedures. Always cross-check literature precedent and practical constraints (starting-material availability, safety, scalability, cost) before laboratory work.
