Photoactivated Formal [3 + 2] Cycloaddition of N-Aryl Cycloprop-ylamines
Bibliographic record
Abstract
Organic transformations initiated by photochemical activation have been at the forefront of reaction discovery. We have seen the [2+2] photocycloaddition performed upon excitation of α,β-unsaturated carbonyl compounds, and more recently [3 + 2] cycloadditions of aryl cyclopropyl ketones have been reported. These methodologies required a photocatalyst and/or external activators, adding some limitations to the substrates used. Herein, we report a formal photochemical [3 + 2] cycloaddition using N-aryl cyclopropylamines and α,β-unsaturated carbonyl systems without the use of photocatalysts or additives. This simple method proceeding through a Single Electron Transfer (SET) offers a wide scope for the synthesis of N-arylaminocycloalkyl compounds in good to excellent yields.

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.
