| Abstract: | A simple and efficient Et3N-mediated transesterification between β-keto esters 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. |
