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
在本文中,我们报道了一种简单且无金属的方法,该方法通过用NH-亚砜肟酮亲核取代N-嗪氮氧化物来合成N-嗪亚砜肟。本方法在室温下具有宽泛的官能团相容性,并提供了几种前所未有的N-嗪亚磺酰亚胺。还发现反应条件适用于对映纯底物和提供的产物,没有任何消旋作用。还发现了其在基于嗪的功能分子如2,2'-联吡啶,1,10-菲咯啉和奎宁的磺化中的应用。
