Herein, we report a palladium-catalyzed method to synthesize 1,4-benzoxazepin-5-ones using salicylamides and propargyl carbonates. The heteroannulation provides a wide range of products in good to excellent yields with broad functional group tolerance. In addition, H2O is used as a low-cost, abundant, and safe solvent, which is important in terms of sustainability.
在此,我们报道了一种使用水杨酰胺和碳酸炔丙酯合成 1,4-苯并氮杂卓-5-酮的钯催化方法。杂环化提供了多种产品,产率良好至优异,并且具有广泛的官能团耐受性。此外,H 2 O被用作低成本、丰富且安全的溶剂,这对于可持续性而言很重要。
