The total synthesis of (±)-trypargine (2) was accomplished to confirm the proposed structure, 1-(3'-guanidinopropyl)-1, 2, 3, 4-tetrahydro-β-carboline. Optically active (-)-trypargine (2a) and its enantiomer (2b) were obtained by the optical resolution of the racemate. The stereochemistry at C-1 is discussed on the basis of the optical rotatory dispersion and circular dichroism curves.
