C2/C4 Regioselective Heteroarylation of Indoles by Tuning C-H Metalation Modes

The development of a rational strategy to achieve the complete regioselectivity and the capability to switch regioselectivity is an appealing, yet challenging, puzzle in transition-metal-catalyzed oxidative Ar-H/Ar-H cross-coupling. Disclosed herein is an iridium-catalyzed C2/C4 regioselective C-H heteroarylation of indoles with the help of a pivaloyl group at the C3 position. The judicious choice of the catalytic systems allows the C2-heteroarylation of indole via a concerted metalation-deprotonation (CMD) process and the C4-heteroarylation via a trimolecular electrophilic substitution (SE3) pathway. The oxidants Cu(OAc)2¡¤H2O and Ag2O are demonstrated to play a vital role in the C2/C4 regioselectivity. In this Article, a heteroaryl-Ir(III)-heteroaryl complex prior to reductive elimination is successfully isolated and characterized, which represents the first example of capturing the bis(hetero)aryl metallic intermediate in oxidative Ar-H/Ar-H cross-coupling. The regiodivergent heteroarylation of indoles developed herein provides an opportunity to rapidly assemble diverse C4- and C2-heteroarylated indoles.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4923-87-9 is helpful to your research. Reference of 4923-87-9

TRANSITION METAL-CATALYZED IMIDATION OF ARENES

The present invention provides novel transition metal complexes (e.g., complexes of any one of Formulae (C1) to (C25)) that include an amine-N-oxide motif. The invention also provides methods of using these transition metal complexes in preparing N-aryl or N- heteroaryl sulfonimides (e.g., compounds of Formula (I)) and aryl or heteroaryl amines (e.g., compounds of Formula (II)). The inventive methods involve imidation of arenes and heteroarenes (e.g., compounds of Formula (A)) using an imidating agent (e.g., a compound of Formula (B), such as N-fluorobenzenesulfonimide (NFBS or NFSI)) in the presence of a single-electron reductant (e.g., an Ag(I) or Ru(II) salt).

Development of a Library of Thiophene-Based Drug-Like Lego Molecules: Evaluation of Their Anion Binding, Transport Properties, and Cytotoxicity

The anion-binding and transport properties of an extensive library of thiophene-based molecules are reported. Seventeen bis-urea positional isomers, with different binding conformations and lipophilicities, have been synthesized by appending alpha- or beta-thiophene or alpha-, beta-, or gamma-benzo[b]thiophene moieties to an ortho-phenylenediamine central core, yielding six subsets of positional isomers. Through 1H NMR, X-ray crystallography, molecular modelling, and anion efflux studies, it is demonstrated that the most active transporters adopt a pre-organized binding conformation capable of promoting the recognition of chloride, using urea and C?H binding groups in a cooperative fashion. Additional large unilamellar vesicle-based assays, carried out under electroneutral and electrogenic conditions, together with N-methyl-d-glucamine chloride assays, have indicated that anion efflux occurs mainly through an H+/Cl? symport mechanism. On the other hand, the most efficient anion transporter displays cytotoxicity against tumor cell lines, while having no effects on a cystic fibrosis cell line.

We describe here a convenient and mild, carbon monoxide gas-free palladium-catalyzed procedure to obtain N-substituted phthalimides with molybdenum hexacarbonyl as carbon monoxide precursor. These conditions tolerate a number of functional groups on the benzene ring as well as a number of amines and give the corresponding phthalimides in good to excellent yields. Copyright

Transition-metal-free decarboxylative bromination of aromatic carboxylic acids

Methods for the conversion of aliphatic acids to alkyl halides have progressed significantly over the past century, however, the analogous decarboxylative bromination of aromatic acids has remained a longstanding challenge. The development of efficient methods for the synthesis of aryl bromides is of great importance as they are versatile reagents in synthesis and are present in many functional molecules. Herein we report a transition metal-free decarboxylative bromination of aromatic acids. The reaction is applicable to many electron-rich aromatic and heteroaromatic acids which have previously proved poor substrates for Hunsdiecker-type reactions. In addition, our preliminary mechanistic study suggests that radical intermediates are not involved in this reaction, which is in contrast to classical Hunsdiecker-type reactivity. Overall, the process demonstrates a useful method for producing valuable reagents from inexpensive and abundant starting materials.

Chromatographic studies of purity and segregation behaviour of natural impurities present in coal tar acenaphthene and pyrene

Twenty one (two unidentified) and 14 impurities were detected and identified in the bottom parts of the zone refined ingots of commercially available ex-coal tar acenaphthene and pyrene, respectively, with the help of Hewlett-Packard gas chromatographs type 6890 GC System and 5890 series II equipped with fused silica capillary columns and the FID and MS detectors. The result of quantitative determination have shown that naphthalene, 2-methylnaphthalene and 9H-fluorene, and 7-methylanthracene, 1-phenylnaphthalene, fluoranthene and unknown compound with the molecular weight of 208 may be treated as the major impurities of the above hydrocarbons, respectively. These results have also shown that with the exception of methyldibenzofuran present as impurity in acenaphthene, the segregation coefficients of all the remaining detected impurities are lower than unity. Moreover, it was found that the final distribution of the major impurities after 100 passes of the melting zone may be described with high accuracy by a third-order equation. The purification procedure worked out on the basis of the determined impurity segregation behaviour enabled the preparation of the hydrocarbons with purity ?99.999mass% from which high quality crystals were grown.

One-pot synthesis and property study on thieno[3,2-: B] furan compounds

Based on the regioselective intermolecular Suzuki coupling and subsequent intramolecular Ullmann C-O coupling reactions, one-pot synthesis of benzo[4,5]thieno[3,2-b]benzofurans (BTBFs) was developed after optimization of the reaction conditions including catalysts, solvents, bases, ligands and reaction times. The one-pot reaction, with only 2 mol% Pd(PPh3)4 and 2 mol% copper(i) thiophene-2-carboxylate (CuTc) as the catalysts, K3PO4¡¤3H2O as the base and tert-butanol as the solvent, afforded moderate to good yields (up to 70%) for a variety of substrates.
