An efficient and expedient approach for the synthesis of unsymmetrical 3,3′-Bis-indolylmethanes via silica gel-mediated Friedel-Craftsalkylation of 3-indolylmethanols with diverse indoles is described. The synthetic utility of this transformation was demonstrated by reusing silica gel up to 10 times without apparent loss of reactivity .

in water at room temperature for synthesis of bis(indolyl)methanes (BIMs) from simple indoles and alcohols is reported. The key step involves the conversion of alcohols to their corresponding carbonyl compounds and subsequent condensation with indoles from in situ generated radicals. Also, the challenging aliphatic alcohols showed good performance in the synthesis of BIMs. We also carried out a detailed
报道了在室温下使用廉价的 K 2 S 2 O 8在水中从简单的吲哚和醇合成双(吲哚基)甲烷(BIM)。关键步骤涉及将醇转化为其相应的羰基化合物,然后与原位产生的自由基中的吲哚缩合。此外,具有挑战性的脂肪醇在 BIM 的合成中表现出良好的性能。我们还对机制进行了详细的探索。

A simple synthetic method to access bis(3-indolyl)methanes (BIMs), key structural components of many value added chemicals including pharmaceuticals, was developed. A tBuOK-mediated route allows to prepare BIMs derivatives, from benzyl alcohols and indoles, in yields of up to 77 % yield. The role of tBuOK was investigated by mechanistic studies that suggest the involvement of radical intermediates
