A copper-catalyzed enantioselective radical C(sp3)−SCF3 coupling of secondary/tertiary benzyl radicals with the easily available (Me4N)SCF3 reagent was developed to afford enantioenriched trifluoromethylthiolated molecules. The key to the success lies in the utilization of chiral phosphino-oxazoline-derived anionic N,N,P-ligands for the reaction initiation and enantioselectivity.
开发了铜催化的对映选择性自由基 C(sp 3 )−SCF 3仲/叔苄基自由基与容易获得的 (Me 4 N)SCF 3试剂的偶联,以提供对映体富集的三氟甲基硫醇化分子。成功的关键在于利用手性膦基恶唑啉衍生的阴离子N,N,P-配体来引发反应并提高对映选择性。
