A straightforward methodology for the selective 2,2,2-trifluoroethoxylation of protected aminoquinoline derivatives at the C5 position has been developed using the 2,2,2-trifluoroethanol as a readily available fluorine-containing source. This transition metal-free process allows, for the first time, the distal and selective formation of a C−OCH2CF3 bond under very mild reaction conditions (0 °C), offering
使用 2,2,2-三氟乙醇作为一种容易获得的含氟来源,开发了一种在 C5 位置对受保护的氨基喹啉衍生物进行选择性 2,2,2-三氟乙氧基化的直接方法。这种不含过渡金属的工艺首次允许在非常温和的反应条件 (0°C) 下选择性地形成 C-OCH 2 CF 3键,为研究目标化合物提供了一种有效的工具。
