Researchers have developed a new structure-aware framework for template-free retrosynthesis, a process crucial for chemical reaction prediction. This method, called RetroDiT, utilizes a graph transformer with rotary position embeddings to explicitly encode the positional importance of reaction center atoms. By prioritizing these critical regions, RetroDiT achieves state-of-the-art performance on benchmark datasets like USPTO-50k and USPTO-Full, outperforming larger models and diffusion methods with significantly less data and computational steps.
