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 BF 3 followed by two highly selective S N 2′ reactions. The key step is the reaction of 2‐(chloromethyl)acrylates with R 2 CuLi/ZnCl 2 reagents which takes place with complete allylic rearrangement.
