Abstract
Abstract Transition‐metal‐catalyzed hydroamination of alkynes with primary amines is a reliable tool for the synthesis of imines and enamines. Intramolecular hydroamination has been successfully applied in the synthesis of biologically relevant compounds, but intermolecular hydroamination is less commonly employed in synthesis, due to the possible formation of multiple regioisomers. With catalyst control, regioselectivity can be defined. This microreview focuses on recent advances in intermolecular alkyne hydroamination with primary amines in the presence of transition‐metal catalysts that are regioselective for anti‐Markovnikov addition. To highlight their potential use in synthesis, some recently developed methodologies that use intermolecular hydroamination in a tandem sequential manner to generate interesting organic cores are also covered.

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
