Late-stage functionalization is a cost-effective method for optimizing drug candidates. This research presents a platform combining geometric deep learning and high-throughput reaction screening to address the challenges of late-stage diversification, focusing on borylation. The computational model accurately predicted reaction yields (4–5% mean absolute error) and classified reactivity of known and unknown substrates (92% and 67% balanced accuracy, respectively). Regioselectivity was also predicted with a classifier F-score of 67%. Applied to 23 diverse drugs, the platform identified numerous diversification opportunities. The influence of steric and electronic factors on model performance was quantified, and a user-friendly reaction format facilitated the integration of deep learning and high-throughput experimentation.
