A facile and modular synthesis of triarylmethanes was achieved in good yield via a two-step sequence in which the final step is the copper(II)-catalyzed arylation of diarylmethanols with arylboronic acids. By using this protocol a variety of symmetrical and unsymmetrical triarylmethanes were synthesized. As an application of the newly developed methodology, we demonstrate a high-yielding synthesis of the triarylmethane intermediate towards an anti-breast-cancer drug candidate.
通过一种简便且模块化的方法,成功地合成了三芳基甲烷,收率良好,该方法包括两步反应序列,最后一步是使用铜(II)催化的芳基硼酸酯与二芳基甲醇进行芳基化反应。通过使用这种方法,合成了各种对称和非对称的三芳基甲烷化合物。作为新开发方法的应用,我们展示了一种高产率的合成方法,用于合成三芳基甲烷中间体,以制备一种抗乳腺癌药物候选化合物。
