Abstract
A palladium-catalyzed, norbornene-mediated ortho-alkylation reaction of aryl iodides with secondary alkyl halides is described. Intermolecular or intramolecular ortho-alkylation proceeds in a domino process with various termination steps, generating two new carbon-carbon or carbon-nitrogen bonds in one pot, to afford an array of polycyclic heterocycles. The use of enantioenriched substrates has shown that this palladium-catalyzed reaction is stereospecific, proceeding with minimal erosion of ee.

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
