Abstract
In this work we report, aluminized polyborate catalyzed facile and efficient one-pot four component Hantzsch synthesis of 1,8-dioxo-decahydroacridines using substituted aromatic aldehydes (1 mmol), dimedone (2 mmol) and ammonium acetate (1.5 mmol) at 95-100oC under solvent-free condition. The prominent advantages of this methodology are good product yields (85-95%), eco-friendliness, mild reaction conditions and use of inexpensive catalyst. The structures of the targeted molecules were examined by FT-IR, 1H-NMR and mass spectral techniques.

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
