molecularly defined NNN−Mn(II) pincer complex catalyzed acceptorless dehydrogenative coupling of alcohols with indoles is reported. A wide variety of symmetrical and unsymmetrical bis(indolyl)methane derivatives as well as some structurally important products such as Vibrindole A, Turbomycin B alkaloid, Antileukemic, and Anticancer agents were synthesized. Mechanistic studies illustrate the importance
本文报道了一种空气稳定的、分子定义的 NNN-Mn(II) 钳形复合物催化醇与吲哚的无受体脱氢偶联。合成了多种对称和非对称双(吲哚基)甲烷衍生物以及一些结构上重要的产品,如 Vibrindole A、Turbomycin B 生物碱、抗白血病和抗癌剂。机理研究说明了 NH 部分在配合物中的重要性以及金属-配体合作在催化过程中的关键作用。
