Thioamide‐Enabled Anodic N‐Centered Radical Cyclizations

ChemElectroChem, Volume 13, Issue 18, 19 September 2026.
This manuscript describes the development of an anodic cyclization route to the bisamine‐heterocyclic core of the chrysosporazine family of natural products. The reaction relies on the oxidation of a thioamidyl anion to generate a N‐centered radical.
