of applications in organic synthesis. Their typical synthesis requires pre-functionalized starting materials and two to three step synthetic sequences. In addition, the selective pre-functionalization of unsymmetrical ketones is a challenge, which limits the synthesis of the desired sulfenylated ketones. To overcome these disadvantages, a metal-free, convenient one-step strategy for synthesizing α-sulfenyl
α-亚磺酰基酮是潜在的前体,在有机合成中有多种应用。它们的典型合成需要预功能化的起始原料和两到三个步骤的合成序列。另外,不对称酮的选择性预官能化是一个挑战,这限制了所需的亚磺酰基化酮的合成。为了克服这些缺点,已经开发了一种无金属,方便的一步法,该方法通过交叉脱氢偶联(CDC)策略在环境温度下合成α-亚磺酰基酮,具有广泛的底物范围。因此,这种CD-S键形成的CDC策略具有吸引力,并可能在有机合成中得到广泛应用。
