ChemistryEurope, Volume 4, Issue 4, April 2026.We report a biosynthesis‐inspired ring distortion approach that involves oxidative ring cleavage, ring rearrangement, and ring expansion reactions from a diverse collection of indole alkaloids and derivatives. This chemical synthesis approach led to the synthesis of >25 distinct chemotypes from 14 indole alkaloids.

Journal of Magnetic Resonance Imaging, Volume 62, Issue 6, Page 1782-1790, December 2025.ABSTRACT Background Ayahuasca is an Amazonian psychedelic brew that contains dimethyltryptamine (DMT) and beta carbolines. Prolonged use has shown changes in cognitive‐behavioral tasks, and in humans, there is evidence of changes in cortical thickness and an increase in neuroplasticity factors that could lead to modifications in functional neural ...

An Efficient, Mild and Solvent-Free Synthesis of Benzene Ring Acylated Harmalines
Molecules, 2009 A facile synthesis of a series of benzene ring acylated analogues of harmaline has been achieved by Friedel-Crafts acylation under solvent-free conditions at room temperature using acyl halides/acid anhydrides and AlCl3.
