Copper-mediated intramolecular oxidative C-H/N-H cross-coupling of alpha-alkenoyl ketene N,S-acetals to synthesize pyrrolone derivatives

CuCl2 and CuBr2-mediated intramolecular oxidative C-H/N-H cross-coupling/halogenation of beta-thioalkyl-substituted alpha-alkenoyl ketene N,S-acetals occurred efficiently, affording 4-halo-5-thioalkyl-3-pyrrolones. Tunable C-S and C-halo bond transformations of the resultant pyrrolone derivatives led to highly functionalized N-heterocyclic compounds.

Synthesis, structure, and fluorescence of isomeric indolizinediones. Carbonyl-bridged isodipyrrinones

In one-pot reactions, pyrrole-alpha- and beta-aldehydes condense readily with 4-ethyl-3-methyl-3-pyrrolin-2-one to give isodipyrrinone analogs, which undergo intramolecular cyclization when the pyrrolealdehyde possesses an alpha or beta-CO2R group. The resulting regioisomeric pyrroloindolizinediones, with structures confirmed by NMR analysis, exhibit strong fluorescence, with quantum yields (phi(F)) as high as 0.91 at lambda(em) similar to 450-550 nm.

Volatile Organic Compounds (VOCs) of Endophytic Fungi Growing on Extracts of the Host, Horseradish (Armoracia rusticana)

The interaction between plant defensive metabolites and different plant-associated fungal species is of high interest to many disciplines. Volatile organic compounds (VOCs) are natural products that are easily evaporated under ambient conditions. They play a very important role in inter-species communication of microbes and their hosts. In this study, the VOCs produced by 43 different fungal isolates of endophytic and soil fungi during growth on horseradish root (Armoracia rusticana) extract or malt extract agar were examined, by using headspace-gas chromatography-mass spectrometry (headspace-GC-MS) and a high relative surface agar film as a medium. The proposed technique enabled sensitive detection of several typical VOCs (acetone, methyl acetate, methyl formate, ethyl acetate, methyl butanol isomers, styrene, beta-phellandrene), along with glucosinolate decomposition products, including allyl cyanide and allyl isothiocyanate and other sulfur-containing compounds-carbon disulfide, dimethyl sulfide. The VOC patterns of fungi belonging to Setophoma, Paraphoma, Plectosphaerella, Pyrenochaeta, Volutella, Cadophora, Notophoma, and Curvularia genera were described for the first time. The VOC pattern was significantly different among the isolates. The pattern was indicative of putative myrosinase activity for many tested isolates. On the other hand, endophytes and soil fungi as groups could not be separated by VOC pattern or intensity.

Synthesis of Pyrrolin-4-ones by Pt-Catalyzed Cycloisomerization in PEG under Microwaves

The unprecedented eco-friendly Pt-catalyzed 5-endo-dig cycloisomerization of readily available a-amino ynones is reported under microwave irradiation in PEG-3400 as reaction matrix. The corresponding pure pyrrolin-4-ones were obtained in excellent yields (80-98%) directly after a straightforward precipitation-filtration workup, thus avoiding any chromatographic purification. The catalytic system was recycled and the chiral purity of all the products was also investigated.

Photocatalytic Conversion of Benzyl Alcohols/Methyl Arenes to Aryl Nitriles via H-Abstraction by Azide Radical

This report presents the visible-light-assisted synthesis of aryl nitriles from easily accessible alcohols or methyl arenes in the presence of O-2. Organic photoredox catalyst, 4CzIPN (1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene), induces single electron transfer (SET) from azide N(3)(-)and generates azide radical N-3(.).The photogenerated N(3)(.)abstracts H atom from alpha-C-H bond of benzylic system, which provides aldehyde and hydrazoic acid (HN3) in situ. This reaction subsequently forms azido alcohol intermediate that transforms into nitrile with the assistance of triflic acid (Bronsted acid). A range of alcohols and methyl arenes successfully underwent cyanation at room temperature with good to excellent yields and showed good functional group tolerance.

Nitrile group as IR probe to detect the structure and hydrogen-bond properties of piperidinium/pyrrolidinium based ionic liquids and acetonitrile mixtures

The use of molecular solvents has been proposed as a simple solution to reduce the high viscosities of neat ionic liquids (ILs) and extend the practical applications of ILs. A proper understanding of the structure and intermolecular interaction is of vital importance for the design, optimization and synthesis of ILs systems with tailored properties for specific applications. In this work, the structure and hydrogen-bond features of the representative pyrrolidinium/piperidinium based ILs and acetonitrile mixtures were studied by a combination of Fouriertransform infrared spectroscopy (FTIR) and density functional theory (DFT) calculations. The nu(C N) region is sensitive to the microenvironment and is used as IR probe to detect the structure and hydrogen-bond properties of the two IL-acetonitrile binary systems in the whole concentration range. Positive peaks are observed in the excess IR spectra of nu(C N) region which indicates the non-ideality of the mixing process and the formation of hydrogen-bonded complexes in the mixtures. With the help of deconvolution and DFT calculations, the species transformation in the mixing process can be identified from the excess spectra: When x(CD3CN) is less than 0.90, acetonitrile mainly interacts with the ion pairs and ion clusters of the ILs. Ion clusters are all broken out into ion pairs and the interaction complex is mainly ion pair-CD3CN when x(CD3CN) > 0.90. In the whole concentration range, the CD3CN cannot break apart the strong coulombic interactions between the cation and anion, and the individual cation and anion do not exist in the mixtures. All of the hydrogen-bonds in the ion pair/ion clusteracetonitrile complexes are weak strength, closed shells and electrostatically dominant interactions. (C) 2020 Published by Elsevier B.V.
