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.

A Strategy for Synthesizing Axially Chiral Naphthyl-Indoles: Catalytic Asymmetric Addition Reactions of Racemic Substrates

A new strategy for enantioselective synthesis of axially chiral naphthyl-indoles has been established through catalytic asymmetric addition reactions of racemic naphthyl-indoles with bulky electrophiles. Under chiral phosphoric acid catalysis, azodicarboxylates and o-hydroxybenzyl alcohols served as bulky but reactive electrophiles that were attacked by C2-unsubstituted naphthyl-indoles, which underwent a dynamic kinetic resolution to afford two series of axially chiral naphthyl-indoles in good yields (up to 98 %) and high enantioselectivities (up to 98:2 er).

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.

Gadolinium Photocatalysis: Dearomative [2+2] Cycloaddition/Ring-Expansion Sequence with Indoles

Lanthanide photocatalysts are much less investigated in synthetic chemistry than rare and expensive late transition metals. We herein introduce Gd-III photocatalysis of a highly regioselective, intermolecular [2+2] photocycloaddition/ring-expansion sequence with indoles, which could provide divergent access to cyclopenta[b]indoles and indolines. A simple and commercially available Gd(OTf)(3) salt is sufficient for this visible-violet-light-induced transformation. The reaction proceeds either through a transient or start-to-end dearomatization cascade and shows excellent regioselectivity (usually >95:5 r.r.), broad scope (59 examples), good functional group tolerance and facile scale-up under mild, direct visible-light-excitation conditions. Mechanistic investigations reveal that direct excitation of the Gd(OTf)(3)/indole mixture gives an excited state intermediate, which undergoes the subsequent [2+2] cycloaddition and cyclobutane-expansion cascade.

Visible Light-Catalyzed Cascade Radical Cyclizatipn of N-Propargylindoles with Acyl Chlorides for the Synthesis of 2-Acyl-9H-pyrrolo[1,2-a]indoles

A novel and convenient visible light-catalyzed tandem radical cyclization of N-propargylindoles with acyl chlorides for accessing 2-aryl-9H-pyrrolo[1,2-a]indoles is established. This transformation involves sequential addition of the acyl radical to the carbon-carbon triple bond, intramolecular cyclization with the 2-position of indole, and isomerization of the carbon-carbon double bond. The experimental results show that this reaction contains a radical pathway and a radical chain process is not the major pathway for the formation of products.

Alkaloids from Tabernaemontana divaricata combined with fluconazole to overcome fluconazole resistance in Candida albicans

Nineteen indole alkaloids including eleven new ones, taberdines A-K (1-11), were isolated from Tabernaemontana divaricata. Their structures were assigned by MS, NMR, single crystal X-ray diffractions, and ECD analyses. Alkaloid 1 is an aspidosperma-type monoterpenoid indole alkaloid and possesses a rearranged pyrrolidine moiety due to C-3 degradation, and 4 has a rare 1,3-oxazolidine moiety within iboga-type alkaloids. Alkaloids 2, 4, 6, and 11-19 combined with 5 mu g/mL fluconazole exhibited significant activity to reverse fluconazole resistance in Candida albicans strains while no one used alone showed any activities against the resistant strain.

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).
