The structure of the Ochrosia alkaloid ochromianine has been established as 11-methoxydihydrocorynantheol [(-)-I] as a result of the racemic and chiral syntheses of the candidate structure I. These syntheses started from the lactim ethers (±)-III and (+)-III, respectively, and proceeded through the intermediates (±)-IV, (±)-VI, and (±)-VIII and through (+)-IV, (+)-VI, and (-)-VIII, respectively.
