Visible Light-Mediated Selective Synthesis of β‑Amino Sulfide Scaffolds via Dual Role of N‑Iodosuccinimide

The synthesis of β-amino sulfides is significant in organic chemistry. However, challenges such as achieving regioselectivity and the limited availability of starting materials remain unresolved. In this study, we present a visible light-mediated method for the selective synthesis of β-amino sulfide scaffolds. Remarkably, two distinct types of β-amino sulfides were selectively synthesized through the dual role of N-iodosuccinimide, which functions as either a reactant or an activator in the construction of the target scaffolds.
