Reactions of Dimethoxycarbene with <i>N</i>‐Tosylated Imines
Bibliographic record
Abstract
Abstract The reactions of dimethoxycarbene (DMC; 2 ), which was generated in situ by thermal decomposition of 2,5‐dihydro‐2,2‐dimethoxy‐5,5‐dimethyl‐1,3,4‐oxadiazole ( 1 ), with N ‐tosylated imines of xanthone and 2,3 : 6,7‐dibenzosuberenone, 3a and 3d , respectively, led to different adducts with rearranged skeletons. In the case of 3a , the 1 : 1 adduct 5 as well as the 2 : 1 adduct 6 were obtained ( Scheme 2 ). The formation of both products can be explained by a migration of a MeO group of the DMC fragment in a zwitterionic intermediate. On the other hand, migration of a Me group of DMC is necessary for the formation of the two 1 : 1 adducts 13 and 14 of 2 and 3d ( Scheme 5 ). The structures of all products have been established by X‐ray crystallography.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
