Photocatalytic Regio‐ and Site‐Selective Alkylamination of Coumarins: Access to 3‐Amino‐ and 4‐Amino Dihydrocoumarins

Photocatalytic Regio‐ and Site‐Selective Alkylamination of Coumarins: Access to 3‐Amino‐ and 4‐Amino Dihydrocoumarins

Functionalized dihydrocoumarins, including 3‐amino‐ and 4‐amino dihydrocoumarins serving as α‐ and β‐amino acid derivatives, have been synthesized using one‐step site‐ and regioselective alkylamination from coumarins. This conversion offers 35 examples in 24% to 81% yields.
