Electrophilic Metal Homoenolates and Their Application in the Synthesis of Cyclopropylamines
Bibliographic record
Abstract
Since their discovery, metal homoenolates have been widely explored as carbon-based nucleophiles for the β-functionalization of carbonyl derivatives. Only recently has it been reported that metal homoenolates can react as carbonyl electrophiles. In this context, we have recently discovered that cyclopropylamines can be prepared from cyclopropanols via zinc homoenolate intermediates. This Synpacts article will present an overview of the reactivity of homoenolates and our strategy to employ these intermediates for the synthesis of cyclopropylamines. Key mechanistic observations and their influence on reaction optimization will also be discussed. 1 Introduction 2 Homoenolates as Nucleophiles—Selected Reactivity 3 Homoenolates as Electrophilic Reagents 4 Conclusion

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.
