Abstract Quinazolin-4(3H)-one structures are highly valued in synthetic chemistry due to their incorporation into diverse natural products and drug molecules. Here, we present a new approach for constructing quinazolin-4(3H)-ones utilizing the reactive N-sulfonoketenimines, generated in situ from terminal alkynes and sulfonyl azides and 2-aminobenzamides in the presence of CuI and Et3N. The reaction
摘要 Quinazolin-4(3 H )-one 结构由于能够融入多种天然产物和药物分子中,因此在合成化学中具有很高的价值。在这里,我们提出了一种利用反应性N -磺基烯酮亚胺构建 quinazolin-4(3 H )-one 的新方法,该反应是在 CuI 和 Et 3 N存在下由末端炔烃、磺酰叠氮化物和 2-氨基苯甲酰胺原位生成的。室温下在 MeCN 中顺利进行,以良好的效率提供目标化合物,并且适合克级合成。 图形概要
