Abstract
Abstract A stereoselective synthesis of isolycoricidine, a natural product belonging to the Amaryllidaceae alkaloids family was produced. In addition, a synthetic study on the main core of lycoricidine led to the formation of analogues and a diastereomer of dihydrolycoricidine. Our strategy was based on an oxidative phenol dearomatization, a stereoselective Heck process, a selective dihydroxylation on a dienone system, several stereoselective reductions, and an oxidative retro‐Michael procedure as an amine‐deprotecting group strategy. Furthermore, two steps highlight the usefulness of hypervalent iodines in total synthesis of natural products.

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
