Regioselectivity in the reaction of β-vinyl-β-propiolactone with various nucleophiles was found to depend on the hard and soft acid and base (HSAB) principle. A hard base such as methoxide ion attacked the acyl carbon exclusively, while the nucleophilic attack of soft bases such as iodide and dialkyl cuprate preferred the terminal vinyl carbon to the β-carbon.
