3-indandione scaffold is an important structural motif used in the preparation of a large number of industrial chemical and pharmaceutical compounds. However, few approaches allow for the direct C2 acylation on these building blocks. A method was developed using DMAP and EDCI, which is mild in reactivity, covers a diverse range of carboxylic acid acylating agents, is compatible with electron releasing
1,3-茚满二酮支架是用于制备大量工业化学和药物化合物的重要结构基序。但是,很少有方法允许在这些构件上直接进行C2酰化。使用DMAP和EDCI开发了一种方法,该方法反应性温和,涵盖了各种羧酸酰化剂,与1,3-茚满二酮配偶体上的电子释放和吸收取代基兼容,并且在极性非质子溶剂中表现良好(由于溶解度原因)该方法干净地提供了25种不同的产物,收率32-96%。
