AiZynthFinder

AiZynthFinder is a free tool for retrosynthetic planning developed at AstraZeneca that C-CAS researchers contributed to. The default algorithm is based on a Monte Carlo tree search that recursively breaks down a molecule to purchasable precursors. The tree search is guided by a policy that suggests possible precursors by utilizing a neural network trained on a library of known reaction templates. This setup is completely customizable as the tool supports multiple search algorithms and expansion policies.
