Asymmetric Rhodium-Catalyzed Allylic Substitution Reactions with Nitrile-Stabilized Carbanions
Bibliographic record
Abstract
Abstract This Account summarizes our recent work on rhodium-catalyzed allylic alkylation reactions with nitrile-stabilized carbanions. Despite the challenges associated with employing nitrile-stabilized nucleophiles in transition-metal-catalyzed reactions, we have developed enantiospecific and enantioselective allylic alkylation reactions. Notably, these novel reactions permit expedient and selective access to an array of acyclic ternary and quaternary stereogenic centers present in important biologically active and functional molecules. 1 Introduction 2 Enantiospecific Allylic Alkylation Reactions with Nitrile-Stabilized Anions 3 Enantioselective Allylic Alkylation Reactions with Nitrile-Stabilized Anions 4 Conclusion

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.
