afford 4-hydroxyquinolines chemoselectively is described. The transformation proceeds through enol tautomerism and a subsequent C-C bond formation. Compared to previous methods, this study provides a new protocol for the construction of 4-hydroxyquinoline compounds from functionalized isocyanides under mild conditions.
描述了铜催化的2-异氰基苯乙酮衍生物的分子内环化反应,以化学方式提供4-羟基喹啉。该转化通过烯醇互变异构和随后的CC键形成而进行。与以前的方法相比,本研究为在温和条件下从官能化异氰酸酯构建4-羟基喹啉化合物提供了新的方法。
