Enantioselective Aromatic Sulfide Oxidation and Tandem Kinetic Resolution Using Aqueous H<sub>2</sub>O<sub>2</sub> and Chiral Iron–Bis(oxazolinyl)bipyridine Catalysts
Bibliographic record
Abstract
An efficient method for the oxidation of aromatic sulfides has been developed by using aqueous H 2 O 2 , catalyzed by the in situ generated chiral Fe/6,6′‐bis(4‐isopropyloxazolin‐2‐yl)‐2,2′‐bipyridine (bipybox‐ i Pr) complex. The corresponding sulfoxides were obtained with high enantioselectivities (up to 98.5:1.5 er ) and in good yields (up to 61 %) when the mono‐oxidation of the sulfides was performed in combination with the kinetic resolution of the sulfoxide into the sulfone.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
