Herein, we describe an efficient transition-metal-free regioselective C3alkylation of indoles for the synthesis of bis(indolyl)methanes and 3-styryl indoles. Nitrobenzene is employed as the oxidant to oxidize the alcohols in the presence of a strong base and the reaction avoids the use of transition metals such as Ru and Mn. The protocol provides a favorable route to access biologically active compounds
在此,我们描述了一种有效的、无过渡金属的吲哚区域选择性C 3烷基化反应,用于合成双(吲哚基)甲烷和3-苯乙烯基吲哚。采用硝基苯作为氧化剂,在强碱存在下氧化醇,该反应避免了过渡金属如Ru和Mn的使用。该方案提供了获取生物活性化合物(如芦丁、vibrindole A 和涡轮霉素 B)的有利途径。
