Abstract
Abstract Starting materials for sustainable total synthesis often come from the chiral pool: carbohydrates, cyclitols, amino acids, and terpenes. In the terpene family, (−)‐sclareol has served as a sustainable, readily available, and versatile chiral building block for the synthesis of numerous natural products. (−)‐Sclareol possesses a unique structure that has consequently promoted its integration as a core framework within various structurally complex and biologically active substances, including sesquiterpenoids, diterpenoids, and sesterterpenoids. (−)‐Sclareol has facilitated access to diverse synthetic key intermediates, promoting the sustainable synthesis of several natural products. Herein, a review is presented covering the recent trends in sustainable total syntheses and the application of chiral pool approaches with emphasis on the preparation of natural products through diverse routes employing (−)‐sclareol as chiral educt. Innovative catalytic and synthetic protocols using (−)‐sclareol are also analyzed and discussed.

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
