The total synthesis of gomisin A and schizandrin having natural configurations were accomplished for the first time. The key feature of these syntheses is a highly efficient intramolecular oxidative coupling of the intermediates 9 and 21, which can be obtained as both enantiomers in optically pure forms. The manipulation of the lactone moieties of 7 and 22 afforded natural enantiomers of schizandrin and gomisin A.
