The direct C3 alkylation of indoles and oxindoles is a challenging transformation, and only a few direct methods exist. Utilizing the underexplored ability of triaryl boranes to mediate the heterolytic cleavage of alpha-nitrogen C-H bonds in amines, we have developed a catalytic approach for the direct C3 alkylation of a wide range of indoles and oxindoles using amine-based alkylating agents. We also employed this borane-catalyzed strategy in an alkylation-ring opening cascade.

1-(Propargyl)indol-2-carbonitriles react with alcohols to afford 1-alkoxypyrazino[1,2-a]indoles under DBU-catalyzed microwave-assisted conditions. The reaction scope includes a wide range of indoles, primary and secondary alcohols, and a thiol. The initial mechanistic study shows that the domino process presumably proceeds through an alkyne allene rearrangement, imidate formation, and nucleophilic cyclization reaction sequence.

This study deals with the synthetic and kinetic aspects of trichloroisocyanuric acid (TCCA) and NaNO2 mediated nitration of indoles in aqueous acetonitrile media under acid-free and Vilsmeier-Haack conditions (using N,N ‘-dimethyl amides) conditions. Nitration of indoles revealed second order kinetics, with a first order dependence on [indole] and [nitrating agent] ([TCCA]/[NaNO2], [(TCCA-DMF)]/[NaNO2] or [(TCCA-DMA)]/[NaNO2], in which [NaNO2] far excess over other reagents). Reactions followed overall second order kinetics with first order in [reagent] and [indole] under the experimental conditions. Isokinetic temperature (beta) values were obtained from Leffler’s equation for different kinetic protocols (beta=303 K (TCCA-NaNO2); 303 K (TCCA-DMF)/NaNO2; and 244 K (TCCA-DMA)/NaNO2). These values are the experimental temperature range (303-323 K) indicating that the entropy factors are probably more important in controlling the reaction.

Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 81-27-6, Name is Sennoside A. In a document, author is Harada, Shingo, introducing its new discovery. Formula: https://www.ambeed.com/products/81-27-6.html.

Despite a growing body of studies on directing-group (DG)-assisted C-H activation strategies, efficient exploitation of the used DG remains underexplored. We developed a rhodium-catalyzed C-H functionalization of indoles at the C4 position using alpha,beta-unsaturated enones as versatile DGs. Combined experimental and theoretical analyses revealed that the C-H activation process was reversible and the course of Rh-carbene generation controlled the overall site-selectivity of the C-H functionalization. The introduced malonate unit and the used enone DG were cyclized in a further C-C bond forming process to assemble 3,4-fused tricyclic indoles in an asymmetric manner. Telescoping the two reaction sequences provided rapid entry into this densely functionalized indole architecture from readily available chemical feedstock.

A series of indole-based helicenes, namely, 15-hexyl-15H-tetraphenyl[1,2-e]indole (HTPI), 14-hexyl-14H-benzo[4′,5′]thieno [2′,3′:7,8]naphtha[1,2-e]indole (HBTNI), 7-hexyl-7H-indolo[5,4-k] phenanthridine (HIPD) and 3-hexyl-3H-phenanthro[4,3-e]indole (HPI) were successfully synthesized by three- or four-step reactions. They exhibited good solubility and high thermal stability of T-d=247, 388, 294 and 251 degrees C, respectively. These compounds emit violet-blue light with maximum emission peaks at 415, 397, 397 and 391 nm in hexane. Among them, HBTNI had excellent thermal stability, narrow and sharp emission peaks, and highest photoluminescence quantum yield (0.32). Thus, HBTNI was an ideal candidate for the violet-blue emitters of OLEDs. Furthermore, the four compounds had two-photon absorption and two-photon excited fluorescence. HTPI showed the maximum TPA with the TPA cross-section (delta) of 171.5 GM at 770 nm. They were rare examples of helicenes with both violet-blue emission and TPA.
