英语翻译
New (S)-pyrrolidinylmethylimidazole ligands (4a-c) have been readily synthesized in a straightforward
fashion from least expensive starting materials in short steps in high yields.Relatively mild and highly
efficient CuI-catalyzed N-arylation procedures for imidazoles with aryl and heteroaryl bromides or chlorides
have been developed in the presence of 4a and Cs2CO3.It is important to note that the protocol could
tolerate functional groups such as ester,nitrile,nitro,ketone,free hydroxyl,and free primary amine on
the aryl halide.The protocol could also be applicable to other ð-electron-rich nitrogen heterocycles (pyrrole,
pyrazole,indole,benzimidazole,and triazole),affording the N-arylazoles in good to excellent yields.

答案

New (S)-pyrrolidinylmethylimidazole这是一个单词吗?还是中间有间隔的?
新的- pyrrolidinylmethylimidazole配体(4a-c)已被以最便宜的原料在短短的步骤里但高产量地以直截了当的方式合成了.为了咪唑类与芳杂环溴化物或氯化物,比较温和但高效催化的n-arylation程序同存在4A及cs2co3已开发.值得注意的是,该议定书可以容忍的功能团体,如酯,腈,硝基,丙酮,游离羟基,游离最初胺对芳卤.该议定书也可以适用于其他ð-电子富含氮化合物(吡咯,吡唑,吲哚,苯并咪唑以及三唑) 并得到产率良好的N-arylazoles.
希望能帮上你的忙.
