Facile synthesis of indolo[3,2-a]carbazoles via Pd-catalyzed twofold oxidative cyclization.

ABSTRACT: A rapid and efficient route has been developed for the synthesis of 9-methoxycarbonylindolo[3,2-a]carbazole derivatives. The key steps in this approach involved an aromatic amination and an oxidative biaryl coupling. Via the present route, indolo[3,2-a]carbazole derivatives are available in 3-4 steps based on commercially available starting materials.

Platinum-catalyzed tandem indole annulation/arylation for the synthesis of diindolylmethanes and indolo[3,2-b]carbazoles.

Project description:Various diindolylmethanes were prepared from propargylic ethers and substituted indoles via a platinum-catalyzed tandem indole annulation/arylation cascade. The resulting diindolylmethanes could be converted to natural product malassezin by formylation or indolo[3,2-b]carbazoles by cyclization.

Synthesis and DNA binding profile of N-mono- and N,N'-disubstituted indolo[3,2-b]carbazoles.

Project description:A series of N-monosubstituted and N,N'-disubstituted derivatives of the indolo[3,2-b]carbazole chromophore have been prepared, and their binding affinity for duplex DNA has been evaluated by ultraviolet and fluorescence spectroscopies. It has been found that indolo[3,2-b]carbazoles bearing basic N-alkyl substituents are intercalators that bind DNA with affinities in the micromolar and submicromolar range and a preference for associating with sequences of mixed composition and purine-pyrimidine steps.

Indolo[3,2-a]carbazoles from a deep-water sponge of the genus Asteropus.

Project description:Two new indolo[3,2-a]carbazoles (1, 2) were isolated from a deep-water collection of a sponge of the genus Asteropus. The structures of 1 and 2 were determined through the analysis of spectroscopic data including mass spectrometry and 2D-NMR. Compound 1 showed minimum inhibitory concentrations of 25 μg/mL against the fungal pathogen Candida albicans and 50 μg/mL against methicillin-resistant Staphylococcus aureus (MRSA). Compounds 1 and 2 showed no cytotoxicity against the PANC1 human pancreatic carcinoma and NCI/ADR-RES ovarian adenocarcinoma cell lines at our standard test concentration of 5 μg/mL.

Synthesis of bicyclic ethers by a palladium-catalyzed oxidative cyclization-redox relay-π-allyl-Pd cyclization cascade reaction.

Project description:Bicyclic ether scaffolds are found in a variety of natural products and are of interest in probe and drug discovery. A palladium-catalyzed cascade reaction has been developed to provide efficient access to these scaffolds from readily available linear diene-diol substrates. A Pd redox-relay process is used strategically to transmit reactivity between an initial oxypalladative cyclization and a subsequent π-allyl-Pd cyclization at remote sites. The reaction affords a variety of bicyclic ether scaffolds with complete diastereoselectivity for cis-ring fusion.

Organometallic indolo[3,2-c]quinolines versus indolo[3,2-d]benzazepines: synthesis, structural and spectroscopic characterization, and biological efficacy.

Project description:The synthesis of ruthenium(II) and osmium(II) arene complexes with the closely related indolo[3,2-c]quinolines N-(11H-indolo[3,2-c]quinolin-6-yl)-ethane-1,2-diamine (L ( 1 )) and N'-(11H-indolo[3,2-c]quinolin-6-yl)-N,N-dimethylethane-1,2-diamine (L ( 2 )) and indolo[3,2-d]benzazepines N-(7,12-dihydroindolo-[3,2-d][1]benzazepin-6-yl)-ethane-1,2-diamine (L ( 3 )) and N'-(7,12-dihydroindolo-[3,2-d][1]benzazepin-6-yl)-N,N-dimethylethane-1,2-diamine (L ( 4 )) of the general formulas [(eta(6)-p-cymene)M(II)(L ( 1 ))Cl]Cl, where M is Ru (4) and Os (6), [(eta(6)-p-cymene)M(II)(L ( 2 ))Cl]Cl, where M is Ru (5) and Os (7), [(eta(6)-p-cymene)M(II)(L ( 3 ))Cl]Cl, where M is Ru (8) and Os (10), and [(eta(6)-p-cymene)M(II)(L ( 4 ))Cl]Cl, where M is Ru (9) and Os (11), is reported. The compounds have been comprehensively characterized by elemental analysis, electrospray ionization mass spectrometry, spectroscopy (IR, UV-vis, and NMR), and X-ray crystallography (L ( 1 ).HCl, 4.H(2)O, 5, and 9.2.5H(2)O). Structure-activity relationships with regard to cytotoxicity and cell cycle effects in human cancer cells as well as cyclin-dependent kinase (cdk) inhibition and DNA intercalation in cell-free settings have been established. The metal-free indolo[3,2-c]quinolines inhibit cancer cell growth in vitro, with IC(50) values in the high nanomolar range, whereas those of the related indolo[3,2-d]benzazepines are in the low micromolar range. In cell-free experiments, these classes of compounds inhibit the activity of cdk2/cyclin E, but the much higher cytotoxicity and stronger cell cycle effects of indoloquinolines L ( 1 ) and 7 are not paralleled by a substantially higher kinase inhibition compared with indolobenzazepines L ( 4 ) and 11, arguing for additional targets and molecular effects, such as intercalation into DNA.

Diastereoselective Synthesis of Highly Substituted Tetrahydrofurans by Pd-Catalyzed Tandem Oxidative Cyclization-Redox Relay Reactions Controlled by Intramolecular Hydrogen Bonding.

Project description:Palladium-catalyzed oxidative cyclization of alkenols provides a convenient entry into cyclic ethers but typically proceeds with little or no diastereoselectivity for cyclization of trisubstituted olefins to form tetrahydrofurans due to the similar energies of competing 5-membered transition-state conformations. Herein, a new variant of this reaction has been developed in which a PdCl2/1,4-benzoquinone catalyst system coupled with introduction of a hydrogen-bond acceptor in the substrate enhances both diastereoselectivity and reactivity. Cyclization occurs with 5-exo Markovnikov regioselectivity. Mechanistic and computational studies support an anti-oxypalladation pathway in which intramolecular hydrogen bonding increases the nucleophilicity of the alcohol and enforces conformational constraints that enhance diastereoselectivity. The cyclization is followed by a tandem redox-relay process that provides versatile side-chain functionalities for further derivatization.

Synthesis of indolo[1,2-c]quinazolines from 2-alkynylaniline derivatives through Pd-catalyzed indole formation/cyclization with N,N-dimethylformamide dimethyl acetal.

Project description:An efficient strategy for the synthesis of 6-unsubstituted indolo[1,2-c]quinazolines is described. The Pd-catalyzed reaction of o-(o-aminophenylethynyl) trifluoroacetanilides with Ar-B(OH)2 afforded 2-(o-aminophenyl)-3-arylindoles, that were converted to 12-arylindolo[1,2-c]quinazolines by adding dimethylformamide dimethyl acetal (DMFDMA) to the reaction mixture after extractive work-up. This reaction outcome is different from the previously reported Pd-catalyzed sequential reaction of the same substrates with Ar-I, Ar-Br and ArN2+BF4-, that afforded 12-arylindolo[1,2-c]quinazolin-6(5H)-ones. Moreover, 12-unsubstituted indolo[1,2-c]quinazolines can be obtained both by reacting 2-(o-aminophenyl)indoles with DMFDMA or by sequential Pd-catalyzed reaction of o-(o-aminophenylethynyl)aniline with DMFDMA.
