A simple and efficient Et3N-mediated transesterification between β-ketoesters and Baylis–Hillman alcohols in toluene solution at reflux using a Dean–Stark apparatus, is described. Allylic esters are exclusively obtained in moderate to good yields, with no trace amounts of γ,δ-unsaturated ketones usually expected from the Carroll decarboxylative rearrangement.
