Abstract
Oxa- and azabicyclic alkenes can be readily activated by transition-metal complexes with facial selectivity, because of the intrinsic reactivity of strained bicyclic structures. Synthetically, these compounds are important synthons that offer an important platform for the construction of biologically/medicinally significant compounds with two or more stereocenters. This Review comprehensively compiles the diverse catalytic processes involving the enantioselective transformations of oxa- and azabicyclic alkenes. It has been organized according to reaction type, including asymmetric ring opening (ARO) reactions, hydrofunctionalizations, cycloadditions and C-H activation reactions. The ARO section has been subdivided based on the type of nucleophiles employed, and further subdivided based on the metal used, with a separate topic dedicated to asymmetric ring-opening metathesis. Lastly, the presentation of each method/group of reactions is accompanied by concise discussions on their advantages and limitations.

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 it
