AI Retrosynthesis Tools Struggle with Complex Natural Products
A new paper on arXiv (2608.07454) examines the limitations of automated retrosynthetic design tools when applied to complex natural products. While these tools, developed over the past fifty years, achieve near-complete success on benchmarks built from catalogued reactions, they falter on densely functionalized, polycyclic natural products that require inventive chemistry. The paper questions whether machines can design such syntheses as expertly as human chemists, highlighting the gap between benchmark performance and real-world frontier challenges.
