((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
((2 S,4 R)-4-羟基N-(2-甲基萘-1-基)吡咯烷-2-羧酰胺(HMNPC),一种由4-羟基-L脯氨酸和2-甲基萘衍生的酰胺1-胺是(杂)芳基卤化物与亚磺酸盐的Cu催化偶联的强配体,首次使(杂)芳基氯化物与NaSO 2 Me发生金属催化偶联。 )芳基氯化物的效果很好,以良好的收率提供了药学上重要的(杂)芳基甲基砜。
