Abstract
Heterocycles are the fundamental structural motifs found in natural products and biologically active compounds. The construction of these structures is therefore an important task in organic chemistry. Vinylethylene carbonates (VECs) are versatile building blocks that can undergo transition metal catalysed decarboxylation to enable various kinds of interesting transformations. This review provides an overview of the significant achievements of VECs in palladium-catalysed annulations over the past five years. The flexible reactivity of VECs is demonstrated by various [3 + 2], [5 + n] and other types of annulations, which could offer powerful protocols for accessing diverse functionalised heterocycles.

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
