Outline
RetroTrim is a system developed to address the problem of irrational or erroneous outputs (hallucinations) in retrosynthesis, a field that has undergone significant changes due to advances in generative models. RetroTrim successfully avoids irrational plans by combining machine learning models with various reaction scoring strategies based on existing chemical databases. This system not only filters out hallucinogenic reactions but also generates the largest number of high-quality pathways overall. RetroTrim won the Standard Industries Million Retrosynthetic Challenge. Furthermore, we propose a novel reaction and synthetic pathway evaluation protocol based on structured reviews by expert chemists. Using this protocol, we compare the systems against 32 new targets, carefully selected to reflect recent trends in drug structure.
