Mono-, bis- and tris-indolyl-substituted furanones useful as color formers, particularly in carbonless duplicating and thermal marking systems, which are prepared respectively by: the interaction of an indole with mucochloric acid; the interaction of an indole with a 4-mono(indolyl)-substituted 4-oxo-2-butenoic acid; and by the interaction of an indole with a 2,4-bis(indolyl)-substituted 4-oxobutanoic acid or with a 3,5-bis(indolyl)-substituted furanone.
A palladium-catalyzed dehydrogenative acylation of indoles using easily accessible aldehydes as the acyl source is described. This reaction provides a new approach for the synthesis of 3-acylindoles.

A series of giant tris(heteroaryl)methanes are easily assembled by one-pot three-componentsynthesis by simple reflux in ethanol without catalyst or additives. Diversely substituted indoles (Ar1) react with quinolinealdehydes, quinolone aldehydes, chromone aldehydes, and fluorene aldehydes (Ar2CHO) and coumarins (Ar3) in 1:1:1 ratio to form the corresponding tris(heteroaryl)methanes (Ar1Ar2Ar3)CH
通过在乙醇中简单回流,无需催化剂或添加剂,通过一锅三组分合成可以轻松地组装一系列巨型三(杂芳基)甲烷。多取代吲哚(Ar 1 )与喹啉醛、喹诺酮醛、色酮醛、芴醛(Ar 2 CHO)和香豆素(Ar 3 )以1:1:1的比例反应生成相应的三(杂芳基)甲烷(Ar 1 Ar 2 Ar 3 )CH 以及 (Ar 1 Ar 1 Ar 2 )CH 三元组。通过取代吲哚与 Ar 2 CHO 的偶联,还合成了一系列新的 2:1 三联体。偶联反应也可以在水中(约 80 °C)进行,但化学选择性优于 (Ar 1 Ar 1 Ar 2 )CH 而不是 (Ar 1 Ar 2 Ar 3 )CH。通过X射线分析证实了代表性(Ar 1 Ar 2 Ar 3 )CH三元组的分子结构。通过与DDQ/HPF 6反应生成模型三(杂芳基/芳基)甲基鎓盐,并通过NMR、DFT和GIAO-DFT进行研究。

Novel alkylindoles that bind tightly to cannabinoid receptors and are neutral antagonists for the cannabinoid 1 receptor and agonists for the cannabinoid 2 receptor are provided. These compounds are useful for treating alcoholism and drug abuse and for treating obesity.
Directarylations of indoles and pyrroles with differently substituted diaryliodonium salts were shown to efficiently proceed in the absence of metal catalysts.
