By the design of suitable starting materials, a silver(I)‐catalyzed epoxide ring‐opening/1,2‐acyl migration/cyclization cascade has been developed, which allowed us to systematically prepare unsymmetrical 3‐formylfurans. Various 3‐formylfurans were prepared in good to excellent yields. In addition, the distinct fluorescence properties of 3‐formylfurans in solution and the solid state are disclosed
通过设计合适的原料,已开发出了银(I)催化的环氧基开环/ 1,2-酰基迁移/环化级联反应,这使我们能够系统地制备不对称的3-甲酰基呋喃。制备了各种3-甲酰基呋喃,收率良好至优异。此外,还公开了溶液和固态中3-甲酰呋喃的不同荧光性质。
