An efficient formal synthesis of (-)-balanol is reported. The ten-step sequence leading to a key precursor 4 features a highly stereoselective synthesis of the functionalized hexahydroazepine core through dynamic kinetic resolution of a racemic alpha -amido beta -keto ester using a ruthenium(II)-catalyzed hydrogenation reaction.
