The visible light-promoted synthesis of N-aroylsulfoximines has been accomplished via an oxidative dehydrogenative coupling at room temperature under air without the addition of a photosensitizer, metal catalyst, or base. This process exhibits good functional group tolerance, allows facile isolation and purification, and affords N-aroylsulfoximines with high efficiency. The efficiency of the newly developed
通过在室温下在空气中通过氧化脱氢偶合而无需添加光敏剂,
金属催化剂或碱,即可实现可见光促进的N-芳酰基亚磺
酰亚胺的合成。该方法表现出良好的官能团耐受性,可以容易地分离和纯化,并且可以高效地提供N-芳酰基亚磺
酰亚胺。使用27个示例详细描述了新开发协议的效率,其收率范围从80%到96%。此外,在所需的N-芳酰基磺
酰亚胺反应产物(<99%ee)中,完全维持了NH-磺
酰亚胺反应的手性。
