Ketene Aminals

An efficient synthesis of bicyclic pyrrolidinones via a cascade reaction of HKAs and N-substituted maleimide in an environmentally friendly medium is described. This protocol uses group-assisted purification (GAP) chemistry. The library of bicyclic pyrrolidinone derivatives has been constructed with moderate to excellent yields.
