Abstract
To identify novel classes of glycine antagonists, compounds potentially useful as neuroprotective after stroke, novel substituted tetrahydroquinoline derivatives, satisfying the key pharmacophoric requirements for glycine antagonists, were designed. To explore the SAR of these compounds an efficient synthetic route was set up exploiting the outstanding reactivity of suitable N-aryl imine derivatives. In particular an allylmetalation reaction or the addition of bis(trimethyldisilyl)ketene acetals allowed the preparation of versatile intermediates which were smoothly transformed into the desired bicycle tetrahydroquinoline derivatives by a Heck-type cyclization reaction.Key words: glycine antagonists, neuroprotection, tetrahydroquinolines, synthesis, allylmetalation.

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
