Retrosynthetic routes are predicted using the ASKCOS web interface tool () using the tree builder module. Settings were chosen to match those used in a previous study evaluating the synthesizability of generative models. Specifically, the maximum tree depth was limited to 9 steps, the maximum branching ratio is set to 25, a maximum wall time of each expansion is limited to 60 s, a maximum reagent cost of $100/g, 1000 max templates, and a maximum target probability of 0.999. Employing these settings along with no defined banned chemicals and reactions for the radical 1(Fig. ), we obtained a total of 43 routes, containing 90 chemicals and 970 reactions.
