Photocatalyst-Free Visible-Light-Induced Cross-Dehydrogenative Sulfenylation of Aminocoumarins and Amino-1,4-naphthoquinones

Key Points

• The aim is to develop a photocatalyst-free method for sulfenylating aminocoumarins with thiols.
• Synthesis of sulfenylated aminocoumarins
• Utilization of blue LED irradiation for reaction facilitation
• No photocatalyst was used in the procedure
• A library of sulfenylated aminocoumarins was successfully synthesized
• The process is efficient under visible light without the need for photocatalysts
