An improved strategy for the effective synthesis of enantiomericallypure (2R,3aS,7aS)-octahydroindole-2-carboxylic acid (Oic), based on the formation of a trichloromethyloxazolidinone derivative, has been developed. Additionally, the completely diastereoselective alpha-alkylation of such oxazolidinone provides a very convenient and conciseroute to enantiopure alpha-tetrasubstituted derivatives of
