Metal-Free Blue-Light-Mediated Cyclopropanation of Indoles by Aryl(diazo)acetates

Blue-light-mediated cyclopropanation of indoles with aryl(diazo)acetates has been developed. The salient features of this strategy are that it is metal-free, operationally simple and atom-efficient, and that it uses an environmentally friendly energy source. In this protocol, blue light was employed as the sole energy source for the transformation. A variety of cyclopropane-fused indoline compounds was obtained in moderate to excellent yields and high diastereoselectivities under mild conditions.

Synthesis and Bioactivity Evaluation of Indole-Thiophene polymer with Molecular Docking Studies

Emulsion polymerization of 2-amino-4-(1-benzyl-1H-indol-3-yl) thiophene-3-carbonitrile (ABITC) using ammonium persulfate (APS) afforded two isomers of (PABITC) with high molecular weight. Chemical structure and morphology of the synthesized polymers were investigated by IR, 1HNMR, SEM, and GPC. Nano-capsulation of ABITC, PABITC, and PABITC/Doxorubicin by polyethylene glycol (PEG) was achieved by the nanoprecipitation method. The anti-proliferative activity of the PABITC and nano-capsulation against HepG2, Huh7, and A549 cancer cell lines were investigated using MTT assay. The result obtained indicates that the encapsulation of ABITC inside PEG-NP led to an improvement in their anti-proliferative activity against cancer cell lines compared to ABITC. The PABITC revealed moderate anti-proliferative activity against tested cells and their encapsulation form with PEG-NP revealed no significant change in the activity. Furthermore, the anti-proliferative activity of PABITC-NP was improved after Doxorubicin (DOX) encapsulation against tested cells compared to PABITC PEG-NP. In addition, PABITC exhibited potent antibacterial activity against tested microbes comparing to ABITC and amikacin. Moreover, the binding mode of the ABITC beside two repeated units inside the active site of the DNA gyrase B chain (PDB ID: 1KIJ) as promising bacterial target and CDK2 enzyme (PDB ID: 1PYE)] as promising cancer target was studied using molecular docking technique.

A DFT study on the mechanism of palladium-catalysed tandem reaction of ortho-electron-deficient alkynyl-substituted aryl aldehydes with indoles

A density functional theory study was carried out to understand the mechanisms of Pd(OAc)(2)-catalysed cyclisation reaction of ortho-electron-deficient alkynyl-substituted aryl aldehydes with nucleophilic attack of indoles leading to the formation indole-substituted indanones in detail. The energy profiles are related to the catalytic cycle, involving alkynyl coordination, 5-exo-dig cyclisation, nucleophilic attack, concerted metalation-deprotonation (CMD), HOAc release, HOAc assisted ring-opening step, and finally alkene insertion to ring rearrangement. Pd(II) coordination with alkynyl and Pd(II) coordination of O of the aldehyde group are latent competitive reaction pathways. The process of indole nucleophilic attack was researched to understand how the alkene interacts with the Pd(II) to facilitate the reactions. When electron-withdrawing group was employed, it plays a key role in controlling the ring size of cyclisation.

Diastereoselective construction of cage-like and bridged azaheterocycles through dearomative maximization of the reactive sites of azaarenes

A highly diastereoselective multicomponent dearomative multifunctionalization of N-alkyl activated azaarenes with 1,5-diazapentadienium salts has been developed, which not only represented a significant advance in maximum utilization of the reactive sites of azaarenes, but also provided a convenient and robust approach to access structurally rigid and synthetically challenging cage-like and bridged azaheterocycles. As an important complement, we also realized the dearomative multi-functionalization of N-aryl azaarenes through an in situ activation strategy. Moreover, the workup-directed selective tri- and bi-functionalization of isoquinolinium salts have been accomplished.

Atom Efficient Magnesiation of N-Substituted Alkyl Indoles with a Mixed Sodium-Magnesium Base

This study presents the alkali metal mediated magnesiation (AMMMg) of three N-alkylated indoles with the mixed Na/Mg base [(TMEDA)Na(TMP)(2)Mg(CH2SiMe3)] 1 (TMEDA = N,N,N ‘,N ‘-tetramethylethylenediamine, TMP = 2,2,6,6-tetramethylpiperidine). All three magnesiated indoles have been successfully characterised by single-crystal X-ray diffraction and solution state NMR studies, whereas iodolysis and Pd-catalysed cross coupling have been investigated. The steric nature of the N-alkyl group changes the reactivity and efficiency of 1 to give either atom efficient disodium tetraindol-2-ylmagnesiates [(Na-TMEDA)(2)Mg(alpha-C9H8N)(4)] 2 and [(Na-TMEDA)(2)Mg(alpha-C10H11N)(4)] 3, or [(TMEDA)Na(TMP)(-C11H12N)Mg(TMP)] 4, whereby only one indole molecule is selectively deprotonated.

Annihilation Delayed Fluorescence of Indole and Carbazole in Liquid Solutions at Room Temperature

The spectra of long-lasting luminescence of indole and carbazole in neutral (cyclohexane) and polar (ethanol) solvents are obtained. The spectra of long-lasting luminescence of indole in these solvents are shifted to longer wavelengths with respect to the fluorescence spectra. The spectra of long-lasting luminescence of carbazole in both solvents coincide with the fluorescence spectra. The long-lasting glow of indole is interpreted as the annihilation delayed fluorescence (ADF) of dimers, while the long-lasting glow of carbazole is attributed to the ADF of monomers. It is suggested that the indole dimers are formed due to the dipole-dipole interaction of molecules in the excited singlet and ground states appearing as a result of the triplet-triplet annihilation. The ADF kinetics is measured, and the lifetimes of the triplet states of indole in cyclohexane are estimated. It is established that the lifetime is determined by quenching of the triplet states by molecules in the ground state. The self-quenching rate constant is found to be 6.2 x 10(7) M-1 s(-1).

Recent Applications of Heteropolyacids and Related Compounds in Heterocycle Synthesis. Contributions between 2010 and 2020

Over the past two decades, polyoxometalates (POM) have received considerable attention as solid catalysts, due to their unique physicochemical characteristics, since, first, they have very strong Bronsted acidity, approaching the region of a superacid, and second, they are efficient oxidizers that exhibit rapid redox transformations under fairly mild conditions. Their structural mobility is also highlighted, since they are complex molecules that can be modified by changing their structure or the elements that compose them to model their size, charge density, redox potentials, acidity, and solubility. Finally, they can be used in substoichiometric amounts and reused without an appreciable loss of catalytic activity, all of which postulate them as versatile, economic and ecological catalysts. Therefore, in 2009, we wrote a review article highlighting the great variety of organic reactions, mainly in the area of the synthesis of bioactive heterocycles in which they can be used, and this new review completes that article with the contributions made in the same area for the period 2010 to 2020. The synthesized heterocycles to be covered include pyrimidines, pyridines, pyrroles, indoles, chromenes, xanthenes, pyrans, azlactones, azoles, diazines, azepines, flavones, and formylchromones, among others.

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 1693-37-4, in my other articles.
