((2S,4R)-4-Hydroxy-N-(2-methylnaphthalen-1-yl)pyrrolidine-2-carboxamide (HMNPC), an amide derived from 4-hydroxy-L-proline and 2-methyl naphthalen-1-amine, is a powerful ligand for Cu-catalyzed coupling of (hetero)aryl halides with sulfinic acid salts, allowing for first time the metal-catalyzed coupling of (hetero)aryl chlorides and NaSO2Me. A considerable number of (hetero)aryl chlorides worked well, providing the pharmaceutically important (hetero)aryl methylsulfones in good to excellent yields.
