chemoselectivity. This reaction proceeds through sequential palladium-catalyzed cyclization and C4–O bond cleavage of oxazolidines to form carbon–carbon and carbon–oxygen double bonds. In addition, the practical value of this method has been explored by conducting a millimole reaction, as well as via the palladium-catalyzed C–H arylation and visible-light-assisted photocatalyzed conversion of the cyclic
报道了一种合成各种N-烯基异喹啉酮的新策略,该策略具有广泛的官能团耐受性和良好的化学选择性。该反应通过连续的钯催化环化和恶唑烷的 C 4 -O 键裂解形成碳-碳和碳-氧双键进行。此外,通过进行毫摩尔反应,以及通过钯催化的 C-H 芳基化和可见光辅助光催化将环状烯酰胺转化为有价值的化合物,探索了该方法的实用价值。
