Abstract The article describes a convenient and efficient synthetic route for the construction of 2-aroylbenzofuran-3-ols from readily available diverse methyl salicylates and phenacyl bromides using K2CO3 as catalyst in dimethylformamide as solvent at room temperature. The reaction involves two steps, which occur in quick succession within 1 h to deliver the product with reasonably high yields. All
摘要 本文描述了一种方便有效的合成路线,用于在室温下以二甲基甲酰胺为溶剂,以 K2CO3 为催化剂,从易得的各种水杨酸甲酯和苯甲酰溴化物中构建 2-芳酰基苯并呋喃-3-醇。该反应包括两个步骤,在 1 小时内快速连续发生,以相当高的收率提供产品。所有合成的 2-芳酰基苯并呋喃-3-醇 (4a-u) 都进行了抗菌研究,其中一些已显示出显着的活性。[本文提供补充材料。访问出版商的 Synthetic Communications® 在线版,获取以下免费补充资源:完整的实验和光谱细节。] 图形摘要
