method for the synthesis of N-azine sulfoximines by the nucleophilic substitution of azine N-oxides with NH-sulfoximines. The present method works at room temperature with wide functional group compatibility and gives several unprecedented N-azine sulfoximines. The reaction conditions were also found suitable with enantiopure substrates and furnished products without any racemization. It also finds

systems for copper-catalyed N-arylations of sulfoximines with arylbromides and aryliodides have been developed. Using 10 mol % of a copper(I) salt in combination with 20 mol % of a 1,2-diamine and Cs2CO3 provides N-arylated sulfoximines in high yields. Various functional groups and heteroatoms are tolarated. The method is complementary to the known protocols for N-arylations of sulfoximines, which require
已经开发了两种简单且廉价的系统,用于亚砜基与芳基溴化物和芳基碘化物的铜催化的N-芳基化。将10摩尔%的铜(I)盐与20摩尔%的1,2-二胺和Cs 2 CO 3结合使用,可以高收率得到N-芳基化亚砜基。各种官能团和杂原子是对等的。该方法是对亚砜亚胺N-芳基化的已知方案的补充,后者需要化学计量的铜盐或成本昂贵的钯/ BINAP催化剂。
