Copper-Catalyzed Aerobic Oxidative Amination of Indole Derivatives via Single-Electron Transfer

An efficient and clean approach for the oxidative amination of indole derivatives with phenothiazines is developed under copper-catalyzed aerobic conditions. The reaction is carried out via the cross-coupling of indole radical cation and phenothiazine radical in air. This approach offers a new perspective in the application of phenothiazine as a nitrogen group source for C-N bond formation reactions.

The Selective N-Functionalization of Indoles via aza-Michael Addition in the Ligand Sphere of a Chiral Nickel(II) Complex: Asymmetric Synthesis of (S)-1H-Indole-Alanine Derivatives

The selective addition of electrophilic C=C double bonds to the N-H bond of indoles is a challenging task due to the high nucleophilicity of indoles at their C3-position. Herein, we report the successful selective intermolecular N-functionalization of various indoles via aza-Michael addition of C=C double bond of a dehydroalanine Schiff base, which takes place in the ligand sphere of a chiral Ni-II complex in the presence of sodium hydride. The resulting hydroaminated Ni-II complexes were isolated in 55-82 % yields with excellent diastereoselectivity (dr > 99:1) (8 examples). And the actual products of interest, namely (S)-2-amino-3-(1H-indol-1-yl)propanoic acids, were subsequently released from the Ni-II complexes via aqueous HCl treatment of the Ni-II complexes and isolated with excellent enantioselectivity (> 99 % ee). The chiral auxiliary [(S)-BPB = (S)-2-(N-benzylprolyl)aminobenzophenone] and Ni-II ions can be easily recovered after the acidic complex cleavage step and reused for the synthesis of the starting Ni-II complex. Moreover, the indole ‘ s preference for nucleophilic attack via its N1- over its C3-position was rationalized by DFT calculations.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 7300-91-6, in my other articles.

Experimental and Theoretical Photoemission Study of Indole and Its Derivatives in the Gas Phase

The valence and core-level photoelectron spectra of gaseous indole, 2,3-dihydro-7-azaindole, and 3-formylindole have been investigated using VUV and soft X-ray radiation supported by both an ab initio electron propagator and density functional theory calculations. Three methods were used to calculate the outer valence band photoemission spectra: outer valence Green function, partial third order, and renormalized partial third order. While all gave an acceptable description of the valence spectra, the last method yielded very accurate agreement, especially for indole and 3-formylindole. The carbon, nitrogen, and oxygen is core-level spectra of these heterocycles were measured and assigned. The double ionization appearance potential for indole has been determined to be 21.8 +/- 0.2 eV by C is and N is Auger photoelectron spectroscopy. Theoretical analysis identifies the doubly ionized states as a band consisting of two overlapping singlet states and one triplet state with dominant configurations corresponding to holes in the two uppermost molecular orbitals. One of the singlet states and the triplet state can be described as consisting largely of a single configuration, but other doubly ionized states are heavily mixed by configuration interactions. This work provides full assignment of the relative binding energies of the core level features and an analysis of the electronic structure of substituted indoles in comparison with the parent indole.

Design, synthesis, antifungal activity, and QM/MM docking study of two azole derivatives with indole ring

Systemic candidiasis is a major health issue for immunocompromised individuals due to the increase in drug-resistance among Candida spp., which are prevalent pathogenic fungi responsible for many types of fungal infections. Azoles are among the most preferred antifungal class for systemic candidiasis with broad antifungal spectrum and systemic availability. In this study, we synthesized and tested antifungal effects of two new indole derivatives to investigate the impact of indole on the activity of azole antifungal compounds and to find potent derivatives against Candida spp. including resistant strains and biofilms. 1-(4-Chlorophenyl)-2-(1H-imidazol-1-yl)ethanol 1H-indole-2-carboxylate (4a) showed excellent antifungal profile with several times more potent activity against the tested species including a fluconazole-resistant C. tropicalis isolate. The minimum inhibitory concentration (MIC) of 4a was 0.03125 mu g/ml against C. albicans, which was 0.5 mu g/ml for fluconazole. The compound also showed promising biofilm inhibitory effect compared to amphotericin B. The importance of indole was demonstrated through molecular docking studies with the structure of C. albicans CYP51, the established target of azole antifungals, using different protocols. QM/MM docking approach yielded excellent results and accuracy, especially regarding metal interactions. As a result, indole could be a very useful fragment to design new and highly potent antifungal compounds in azole structure.

CHARACTERISTICS OF INDOLE AEROBIC DEGRADATION SLUDGE REINFORCE TRAINING AND THE RESEARCH OF DEGRADATION EFFICIENCY

To improve the treatment effect in the pharmaceutical wastewater in the biochemical system, the experiment domesticated efficient aerobic activated sludge to deal with wastewater deeply. In the presence of glucose co-matrix, indole was used as the characteristic pollutant to acclimate aerobic activated sludge by increasing pollutant concentration. The degradation characteristics and microbial characteristics during training were studied. The experimental results showed that indole could inhibit the growth of microorganisms in activated sludge, but after 2 months of intensive culture, activated sludge could adapt to the environment in which indole was the only carbon source. The bacteria species in the sludge were mainly Comamonas (34.18%) and Acinetobacter (15.45%), which could treat indole with a concentration of 200mg/L, the degradation efficiency was increased from 80% to more than 98.6%, and the SOUR value was stable at more than 7.61 mgO(2)/g MLSS.h, which was suitable for application in advanced treatment engineering of indole-containing pharmaceutical wastewater.
