Abstract
Abstract A new, catalytic methodology for the synthesis of heterobiaryls by the ruthenium‐catalyzed CH activation/cross‐coupling of heterocyclic amides with aryl boroneopentylates is surveyed. From this survey, the highly regioselective reaction of furan‐3‐carboxamide to give 2‐aryl‐3‐furanamides is optimized and generalized in scope with respect to the aryl boroneopentylate coupling partners. Established thereby is a one‐step synthetic method which may supercede the broadly applied two‐step directed ortho metalation (DoM)–cross coupling reaction involving cryogenic and strong base conditions and which has potential for further ortho and remote metalation chemistry. magnified image

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
