摘要
（（2S,4R）-4-Hydroxy-N-（2-methylnaphthalen-l-yl）pyrrolidine-2-carboxamide （HMNPC）, an amide derived from 4-hydroxy-L-proline and 2-methyl naphthalen-l-amine, is a powerful ligand for Cu-catalyzed coupling of （het- ero）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 im- portant （hetero）aryl methylsulfones in good to excellent yields.
