A highly selective synthesis of conjugated polyene sulfonyl derivatives is described via the elimination of disulfonyl chloride with readily accessible raw material dihaloalkane. The protocol offers a convenient way to form sulfonamides, sulfonates and even sulfones. Furthermore, this method was manipulated under mild condition with simple operation in high yield to afford only trans products.
通过用容易获得的原料二卤代烷烃消除二磺酰氯,描述了共轭多烯磺酰基衍生物的高选择性合成。该协议提供了一种方便的方法来形成磺酰胺,磺酸盐甚至砜。此外,该方法在温和条件下以高产率简单操作进行操作,仅得到反式产物。
