A new chemical method produces ibogaine in seven steps from pyridine, enabling gram-scale synthesis. This approach also creates three additional iboga alkaloids, the unnatural enantiomer (+)-ibogaine, and four analogues. Biological tests show that (+)-ibogaine does not affect cortical neuron growth like natural ibogaine, while (-)-10-fluoroibogamine strongly promotes neuron growth and potently modulates the serotonin transporter. The work provides a platform for making iboga alkaloids and related compounds for further study, supporting research into their therapeutic potential for addiction and other neuropsychiatric conditions.
