Abstract
Acyl substituted triazoles are valuable scaffolds, but the direct synthesis of these moieties from terminal alkynes by copper catalysis remains unexplored. We report a robust, general, and efficient method using a simple CuI/2,2'-bipyridine catalytic system. This transformation involves a copper catalyzed azide-alkyne cycloaddition (CuAAC) followed by an intramolecular acylation onto a carbamoyl chloride. The reaction proceeds under mild conditions, tolerates several functional groups, and is readily scalable. This method represents a novel strategy towards the synthesis of complex heterocycles by a CuAAC/acylation domino process.

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
