The Silyloxy-Cope Rearrangement of Syn-Aldol Products: Evolution of a Powerful Synthetic Strategy
Bibliographic record
Abstract
All articles of this category Enantiomerically pure 1,5-hexadienes incorporated into a silylated aldol structure undergo rapid, clean, high-yielding and highly stereoselective Cope rearrangements. The 7-oxo-2-enimides thus obtained are formally the products of a γ -1,4-selective addition of a metal dienolate to an α , β -unsaturated aldehyde - a transformation which current methodology can not accomplish directly and stereoselectively. They have proved to be very useful synthetic intermediates en route to highly substituted oxygen and nitrogen heterocycles, functionalized cyclohexanes, and 1,3,5,‥-polyol chains. aldol products - asymmetric synthesis - Cope rearrangement - cyclohexanes - heterocycles - polyols

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
