When Indoles Meet Allene and its Derivatives

The allene functional group and the indole ring have emerged as recurring building blocks in organic chemistry due to their diverse reactivity and straightforward preparation. In addition, the biological properties and natural occurrence of indole give a remarkable added-value to newly-prepared indole-based structures. In the last decade, the combination of allenes and indoles as co-reactants has revealed a fruitful reactivity allowing the synthesis of complex structures and the investigation of new mechanistic pathways, such as the challenging asymmetric nucleophilic addition using optically pure allenes as chirality transfer agents, the double nucleophilic addition through metal carbene intermediates, or novel hybrid catalysis in a bimetallic system. Herein we report a critical review into the wide and fascinating ways allenes and indoles can interact, and the structural diversity that can be therefore achieved.

Reference of 123-11-5, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 123-11-5.

Direct Synthesis of Structurally Divergent Indole Alkaloids from Simple Chemicals

A direct and structurally divergent synthesis of indole alkaloids from very simple 2-vinylanilines, alkynes and TBN via a novel substrate fragmentation/cycloaddition strategy has been developed, which provides an efficient noble-metal-free approach to access a library of highly valuable indole derivatives of tryptamines and tryptamine-related oximes, lactams, and lactones, as well as -carbolines, spiroindolines, and hexa-hydropyrrolo[2,3-b]indoles.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 298-46-4. Name: Carbamazepine.

Palladium-Catalyzed Silacyclization of (Hetero)Arenes with a Tetrasilane Reagent through Twofold C-H Activation

The use of an operationally convenient and stable silicon reagent (octamethyl-1,4-dioxacyclohexasilane, ODCS) for the selective silacyclization of (hetero)arenes via twofold C-H activation is reported. This method is compatible with N-containing heteroarenes such as indoles and carbazoles of varying complexity. The ODCS reagent can also be utilized for silacyclization of other types of substrates, including tertiary phosphines and aryl halides. A series of mechanistic experiments and density functional theory (DFT) calculations were used to investigate the preferred pathway for this twofold C-H activation process.

Dehydrogenation of the Liquid Organic Hydrogen Carrier System Indole/Indoline/Octahydroindole on Pt(111)

Indole derivatives are considered as promising liquid organic hydrogen carriers for renewable energy storage. Using X-ray photoelectron spectroscopy, temperature-programmed desorption, and infrared reflection absorption spectroscopy, we investigated low-temperature adsorption and dehydrogenation during heating of indole, indoline, and octahydroindole on Pt(111). For all three molecules, we find deprotonation of the NH bond above 270 K, accompanied with dehydrogenation of indoline and octahydroindole via an indole intermediate, resulting in an indolide species above 300 K. For octahydroindole, we also find a side reaction yielding small amounts of a pi-allyl species between 170 and 450 K. Above 450 K, decomposition of the remaining indolide species takes place.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 88-15-3 help many people in the next few years. Computed Properties of C6H6OS.

Efficient Synthesis of Fused and Bridged Cyclic Pyrrolo[3,4-a]carbazoles via NH4I Promoted Three-component Reaction

NH4I promoted three-component reaction of indoles, cyclic ketones and maleimides in toluene at 140 degrees C afforded polysubstituted cyclic fused pyrrolo[3,4-a]carbazoles in good yields. The reaction mechanism included sequential Lewis acid catalyzed 3-alkenylation of indole, Diels-Alder reaction and aromatization process. More importantly, the similar NH4I promoted reaction of indoles and acetophenones with two molecules of maleimides in refluxing toluene resulted in the complex tetrahydro-4,10a-[3,4]epipyrrolopyrrolo[3,4-a]carbazoles in satisfactory yields via double Diels-Alder reaction. On the other hand, tetrahydropyrrolo[3,4-a]carbazoles can be easily prepared in high yields by conc. HCl catalyzed three-component reaction of indole and acetophenone and one molecules of maleimide in refluxing ethanol.

Straight Access to Indoles from Anilines and Ethylene Glycol by Heterogeneous Acceptorless Dehydrogenative Condensation

The development of original strategies for the preparation of indole derivatives is a major goal in drug design. Herein, we report the first straight access to indoles from anilines and ethylene glycol by heterogeneous catalysis, based on an acceptorless dehydrogenative condensation, under noninert conditions. In order to achieve high selectivity, a combination of Pt/AL(2)O(3) and ZnO have been found to slowly dehydrogenate ethylene glycol generating, after condensation with the corresponding pyrrole-ring unsubstituted indoles.

Enhanced carbon dioxide capture in an indole-based microporous organic polymer via synergistic effects of indoles and their adjacent carbonyl groups

A carbonyl-functionalized indole-based microporous organic polymer (PKIN) was designed and synthesized in the presence of the FeCl3 catalyst by a facile direct oxidative coupling reaction. Taking advantage of the synergistic effect of indoles and their adjacent carbonyl moieties on carbon dioxide (CO2), the CO2 uptake capacity of the polymer reaches up to 6.12 mmol g(-1) (1.0 bar, 273 K) with high gas selectivities, making the polymer a promising microporous material for the application of CO2 separation and capture, and the proposed synergistic effect is expected to be a new rationale for the design of CO2 capture materials.
