A mild silver-catalyzed decarboxylative acylation of coumarins has been developed by using α-oxocarboxylic acids as acyl sources. This protocol provides an efficient and straightforward access to aroyl substituted coumarins in moderate to excellent yields with good selectivities. Furthermore, the reaction conditions were also applicable to quinolinones and naphthoquinones, affording the corresponding
通过使用α-氧代羧酸作为酰基源,已开发出温和的银催化香豆素的脱羧酰化反应。该方案以中等至极好的收率和良好的选择性,提供了直接,有效地获得芳酰基取代的香豆素的途径。此外,反应条件也适用于喹啉酮和萘醌,得到相应的酰化杂环化合物。
