    Notes: The title products are prepared via an efficient three-step synthesis which involves hydroalumination of methyl propiolate and Lewis-acid-promoted reaction with acetone in the presence of BF3 followed by two highly selective SN2′ reactions. The key step is the reaction of 2-(chloromethyl)acrylates with R2CuLi/ZnCl2 reagents which takes place with complete allylic rearrangement.
