Abstract
Abstract The pentafluorosulfanyl (‐SF 5 ) functional group is of increasing interest as a bioisostere in medicinal chemistry. A library of SF 5 ‐containing compounds, including amide, isoxazole, and oxindole derivatives, was synthesised using a range of solution‐based and solventless methods, including microwave and ball‐mill techniques. The library was tested against targets including human dihydroorotate dehydrogenase (HDHODH). A subsequent focused approach led to synthesis of analogues of the clinically used disease modifying anti‐rheumatic drugs (DMARDs), Teriflunomide and Leflunomide, considered for potential COVID‐19 use, where SF 5 bioisostere deployment led to improved inhibition of HDHODH compared with the parent drugs. The results demonstrate the utility of the SF 5 group in medicinal chemistry.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
