A one pot synthesis of 2-methy lindole analogues and skatole dimers of biological interest using excess amounts of the substrates and the catalyst and higher temperature underFriedel-Crafts acylation conditions is reported. The products were defined by spectroscopic and single crystal X-ray analysis. Rationalization for the formation of the products has also been attempted.

A simple heterogeneously palladium-catalysed procedure for the selective C3-arylation of indoles is reported. Under relatively standard reaction conditions (Pd-catalyst, K(2)CO(3), dioxane, reflux), using only 1 mol % [Pd(NH(3))(4)]/NaY as the catalyst, indoles substituted or not at position 2 gave up to 92% conversion (i.e., 85% isolated yield) towards the expected C3-arylated indole.

1-(4-Aminophenyl) indoles optionally substituted on the 2-,4-,5-,6- and 7- positions of the indole ring and on the amino group on the 4- position of the phenyl ring, which indoles inhibit IL-2 production in T-lymphocytes.
KO<sup><i>t</i></sup>Bu-Mediated Aerobic Transition-Metal-Free Regioselective β-Arylation of Indoles: Synthesis of β-(2-/4-Nitroaryl)-indoles
flask. By using this mild and economical methodology, syntheses of β-(2/4-nitroaryl)-indoles with sensitive functionalities such as bromo, iodo, cyano, and nitro were achieved chemo- and regioselectively. Synthesized β-(2/4-nitroaryl) indoles were transformed into densely functionalized biindoles, indoloindoles, and (4-aminoaryl)-indoles which demonstrate post-transformation utility of the developed methodology
在室温下,在开放式烧瓶中的DMSO中,存在KO t Bu介导的硝基芳烃与吲哚的分子间氧化C–C偶联。通过使用这种温和且经济的方法,可以选择性地实现具有溴,碘,氰基和硝基等敏感功能的β-(2 / 4-硝基芳基)-吲哚的合成。合成的β-(2 / 4-硝基芳基)吲哚被转化为高密度官能化的双吲哚,吲哚吲哚和(4-氨基芳基)-吲哚,证明了所开发方法的转化后效用。
