Abstract
The synthesis and applications of carboxy-MIDA-boronate, a novel C1 building block, are described. This molecule is accessible via a ruthenium tetraoxide-mediated cleavage of commercially available ethynyl-MIDA-boronate. In the course of this study, carboxy-MIDA-boronate was found to possess ambident reactivity towards nucleophiles. Carboxylic acid derivatization produces a broad range of previously unknown carbamoyl-, oxycarbo- and thiocarboboronates. Carboxy-MIDA-boronate and its derivatives undergo condensations to access borylated heterocycles with boron at positions that are difficult to access using alternate methods. The resulting heterocycles participate in the Suzuki-Miyaura cross-coupling reaction, enabling entry into diverse bis(heteroaryl) motifs. The carbon monoxide-releasing capacity of carboxy-MIDA-boronate was also examined and applied in palladium-catalyzed carbonylation.

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
