optimized reaction conditions are well suited to the task of N-vinylation of sulfoximine with trans-2-phenylvinylboronic acid. N-Arylation of sulfoximines with different arylboronic acids, including sterically hindered boronic acids, is achieved using copper(I) iodide and 4-DMAP at room temperature. Moreover, N-arylation of biologically relevant l-methionine sulfoximine is demonstrated for the first time

[reaction: see text] Copper-mediated cross-coupling reactions of sulfoximines with aryl iodides and aryl bromides provide N-arylatedsulfoximines in high yields. The method is complementary to the known palladium-catalyzed N-arylation and allows the preparation of N-arylatedsulfoximines, which have previously been inaccessible.

Palladium-catalyzed C–N bond coupling reaction between NH-sulfoximines and aryl halides (e.g., −Br, −I, and −Cl and pseudohalides −OTf and −ONf) was successfully achieved. Nevertheless, aryltosylates/mesylates left much to be achieved. In this report, a general N-arylation of sulfoximines with aryl sulfonates is described. Using Pd(OAc)2/MeO-CM-phos complex, the N-aryl sulfoximine products can be

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。

An inexpensive and experimentally simple, iron-catalyzed N-arylation reaction of NH-sulfoximines with aryliodides is reported. This complementary method to the known palladium- and copper-catalyzed ones features the use of a combination of environmentally friendly FeCl3 and N,N′-dimethylethylenediamine (DMEDA) as catalytic system and allows the efficient preparation of various N-arylsulfoximines in
