Enantioselective syntheses of several paraconic acids have been achieved using catalyzed asymmetric hydrogenation of β-keto esters with SYNPHOS® as a ligand. This strategy allowed the short synthesis of biologically active (−)-methylenolactocin 1, (−)-protolichesterinic acid 2, (−)-phaseolinic acid 3 and (+)-roccellaric acid 4.
