Abstract

fetched live from OpenAlex

Computational asymmetric catalysis has seen an impressive rise in the last twenty years, thanks to advancements in algorithm and method development for predicting catalyst enantioselectivity. These methods/algorithms describe reactions that can be categorized into two groups: reactions where 1) knowledge of the mechanism is not required and where leveraging experimental data to establish correlations between reaction descriptors and enantioselectivity is imperative, and 2) the mechanism (or transition state (TS) for the enantioselective step) is known and used to determine catalyst stereoselectivity by modeling the diastereomeric TSs. Although these methods have reached an important level of proficiency for enantioselectivity prediction, this field remains largely obscured for experimental chemists. In this review, we aim to shed light on models, methods, and applications used in asymmetric synthesis, with accessible language suited for experimental chemists. Our hope is that these methods will ultimately be adopted by synthetic chemists for the design of novel catalysts.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
