  One-Pot Construction of 3,3′-Bisindolylmethanes through Bartoli Indole Synthesis

  摘要：

  A one-pot approach to 3,3'-bisindolylmethane derivatives from nitrobenzene derivatives through the Bartoli indole synthesis was developed, in which the acid used to quench the reaction markedly affected its outcome. Quenching the reaction with concd HCl produced 3,3'-bisindolylmethane in contrast to the formation of 7-substituted indole by quenching with NH4Cl.

• Regioselective C₃Alkylation of Indoles for the Synthesis of Bis(indolyl)methanes and 3-Styryl Indoles

  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。
