Abstract
Chemical transformation of nitroso acetals derived from tandem [4 + 2]/[3 + 2] cycloadditions of nitroalkenes have been investigated. New reduction methods were surveyed in an attempt to supplant the use of hydrogen and Raney nickel. Homogeneous catalytic hydrogenation was not successful, but samarium diiodide did effectively and selectively cleave one of the NO bonds in a number of nitroso acetals. Acid-promoted hydrolysis of the nitroso acetals produced both α-alkoxy nitrones and hydroxamic acids selectively via expected pathways.Key words: nitroso acetals, hydroxamic acids, α-alkoxy nitrones, reduction, hydrolysis.

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
