A novel, dichloroketene-chiral enol ether cycloaddition-based synthesis of enantiopure (+)-preussin and (-)-AHPPA has been realized. The efficient, highly stereoselective approach, which involves a Beckmann ring expansion reaction to access the key pyrrolidinone, proceeds in ca. 16% overall yield for each of the compounds.
