Enantiomericallypurepyrrolidinones were synthesized as endothelinreceptorantagonists. A [2+2] cycloaddition of an imine and an enantiomericallypure acid chloride gave two diastereomeric β-lactams which were separated and rearranged to give the enantiomericallypurepyrrolidinones which could be reduced to give the corresponding pyrrolidines.
