Abstract
A study on the activation of the NC–H bond of Morita–Baylis–Hillman adducts of N-substituted isatin with cerium ammonium nitrate (CAN) and saturated and unsaturated alcohols have been carried out. The choice of a Morita–Baylis–Hillman adduct for this study is screened with a number of adducts. A comparative and reactivity pattern study on NC-H activation of Morita–Baylis–Hillman adducts of N-substituted isatin derivatives viz. N-methyl, N-ethyl, N-methyl acetate, N-benzyl, N-propargyl, and N-isopropyl isatins have been carried out. Effect of aryl ring substitution has also been investigated. A plausible mechanism for the formation of the ether products has been outlined.

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
