Biosynthetically‐Inspired Oxidative Cleavage Platform Enables Rapid Access to Diverse and Architecturally Complex Chemotypes From Indole Alkaloids

open access: yesChemistryEurope, 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.
