propiolate and ethyl buta-2,3-dienoate with cyclohexanone induced by SmI2 occurred either at α- or β-position to yield different products depending on with or without a proton source. The synthesis of terpenic acid was demonstrated using this reaction.

Copper-Catalyzed One-Pot Borylative Aldolisation β-Fluoride Elimination for the Formal Addition of Acrylates to Carbonyl Moieties
borylation/aldolisation of methyl 2‐fluoroacrylate with carbonyl compounds followed by an elimination to give Morita–Baylis–Hillman (MBH) analogues. The optimal conditions described were shown to be compatible with a wide range of aldehydes and ketones. Unprecedented MBH adducts derived fromketones were efficiently synthesized.
