Abstract

fetched live from OpenAlex

An unusual example of the abnormal Wolff rearrangement was studied. The bicyclic structure of the reactant and intermediates precluded some mechanistic possibilities of this unusual Abnormal Wolff Rearrangement. The study involved the photochemical rearrangement of diazodehydronorbornone bearing phenyl and 2-pyridyl groups at C-7. A number of examples of interesting stereoselectivity were encountered. The mechanism was investigated by use of ab initio QST type computations which located a unique transition structure species accounting for the reaction mechanism.Key words: abnormal-Wolff, carbene, rearrangement, QM computations, reaction mechanism.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
