The enantiomericallypure pyrrolidine diester 4 is a useful buildingblock for the synthesis of chiral hydroporphyrin compounds. Treatment of optically active aromatic amines with bislactone 5 gave pairs of N-alkylated lactam-lactone diastereomers 6 and 8. These diastereomers were separated by MPL chromatography and in the case of 8 they could be debenzylated to yield the enantiomericallypure lactam-lactone
