Herein we reported an efficient palladium-catalyzed enantioselective arylation of both alkyl and aryl sulfenate anions to deliver various chiral sulfoxides in good yields (up to 98%) with excellent enantioselectivities (up to 99% ee) by the use of our developed chiral O,P-ligands (PC-Phos). PC-Phos are easily prepared in short steps from inexpensive commercially available starting materials. The single-crystal
在此,我们报道了一种有效的钯催化对映选择性芳基化烷基和芳基次磺酸根阴离子,通过使用我们开发的手性 O,以良好的收率(高达 98%)和优异的对映选择性(高达 99% ee)提供各种手性亚砜, P-配体(PC-Phos)。PC-Phos 很容易从廉价的市售起始材料中以短步骤制备。PC4/PdCl2 的单晶结构表明,通过与钯 (II) 中心的 O,P 配位形成了一个很少观察到的 11 元环。该方法的显着特点包括底物范围广、易于放大、适用于生物活性化合物的后期修饰以及市售药物舒林酸的合成。
