Double the fun: The title reaction was developed by using a Lewis base/iminium activationstrategy (see scheme). The reaction proceeded with excellent yields and ee values, and the products were additionally transformed into a single enantiomer of a substituted pyrrolidine with excellent retention of configuration.
