cross-coupling reactions of α-bromoaryl NH-sulfoximines with elemental sulfur lead to benzo[d][1,3,2]dithiazole-1-oxides, which represent a new class of three-dimensional heterocycles. The reactions proceed under mild conditions showing good functional group and heterocycle tolerance. By imination/oxidation, the initial cross-coupling products can be converted to unprecedented cyclic sulfonimidamides
铜催化的 α-溴芳基N H-亚砜亚胺与元素硫的交叉偶联反应生成苯并 [ d ][1,3,2] 二噻唑 -1-氧化物,它代表了一类新的三维杂环。反应在温和的条件下进行,显示出良好的官能团和杂环耐受性。通过亚胺化/氧化,最初的交叉偶联产物可以转化为前所未有的环状磺酰亚胺衍生物。此外,通过钌催化的与丙炔酸乙酯的环扩展获得了七元杂环。
