Signal amplification by reversible exchange (SABRE) is a para-hydrogen-based technique that utilises a metal complex, normally centred on iridium, to propagate polarisation from para-hydrogen-derived hydride ligands to spin-½ nuclei located in a bound substrate. To date, substrates possessing 1H, 13C, 15N, 19F, 31P, 29Si, and 119Sn nuclei have been polarised by this technique. The exact positioning of these nuclei has a direct bearing on the enhancement observed and so substrates must be chosen or synthesised with care in order to maximise polarisation transfer, and hence the resulting enhancement. The chemical composition of the metal complex must be similarly appraised, as the exchange rate of substrates and para-hydrogen is implicated heavily in efficient polarisation transfer. The nature of the polarisation transfer, whether homogenous or heterogeneous, is another important facet to consider here, as is conducting SABRE in water-based systems. This review discusses the physical and theoretical aspects of the SABRE experiment, as well as the applications of the SABRE technique, namely, the detection of analytes at concentrations far below what would be possible with conventional NMR techniques and the collection of hyperpolarised magnetic resonance images. Advances relating to utilising singlet states for SABRE, pulse sequence design and the nature of the polarisation transfer mechanism are also discussed, and the implications for future SABRE-based discoveries highlighted.

(Chemical Equation Presented) A short stereoselective total synthesis of the polyketide natural product, tarchonanthuslactone, has been achieved. The key sequence involves the first reported catalytic enantioselective reduction of an N-acyl pyrrole and subsequent use of this stereocenter in a diastereoselective reductive cascade. This proceeded with unprecedentedly high stereocontrol and offered an elegant method of generating the desired syn stereochemistry present in the final target in one step.

The photoassisted degradation of aromatic heterocycles (pyrrole, imidazole, pyrazole, isoxazole, oxazole and thiazole) and N-containing alicycles (aliphatic heterocycles: pyrrolidine, 4-butanelactam and 5-pentanelactam) was examined in liquid-solid dispersions. Complete mineralization (TOC) of the aromatic heterocycles was attained within ca. 1 h of UV irradiation of the TiO2/heterocycle system in acidic (pH 3), near-neutral (pH 6.0-7.6) and alkaline (pH 11) media. Mineralization kinetics were, in general, not appreciably influenced by the presence of acid but tended to be somewhat slower in alkaline media. N-alicycles were photomineralized more slowly than were the aromatics. The former could be mineralized in acidic and near-neutral media in less than 2 h, but not in alkaline media in which pyrrolidine, 4-butanelactam and 5-pentanelactam (and for comparison 4-butanelactone) were not mineralized even after 3 h of UV irradiation. Final products were, in all cases, CO2, NH4+ and NO3- ions and SO42- ions in the case of thiazole. Nitrogen (N2) gas was detected only during the photooxidation of pyrazole (contains two adjacent N heteroatoms) but not imidazole in which the N atom are separated by a C atom. The molar ratio NH4+/NO3- depended closely on the chemical structure of the substrates at the longer irradiation times. The site and mode of adsorption of these heterocycles onto the TiO2 particle surface were inferred from point charge calculations and the point of zero charge of the TiO2 (pHpzc ?6.7); the position of elecrophilic attack by the photogenerated {radical dot}OH radicals was deduced from calculated frontier electron densities.

Global spreading of antibiotic resistant microorganisms and genes calls for the development of effective strategy to eliminate antibiotic pollution from the environment. Tetrahedral silver phosphate (Ag3PO4) is one of the master visible light photocatalysts but encountered the drawback of low stability due to photocorrosion. Integration of Ag3PO4 with N-doped reduced graphene oxide (N-rGO) that has large specific surface area, ample functional groups and hetero atoms doping is anticipated to overcome the problem. Thus, the present study prepared high stability Ag3PO4@N-rGO hybrid catalysts and applied for detoxification of sulfamethoxazole (SMX). Further, the operational parameters towards the photocatalytic degradation was systematically optimized to maximize the efficiency through response surface methodology (RSM) based on central composite design (CCD). The parameters that influenced the SMX degradation efficiency was as follows: pH > N-content > catalyst dosage. Under the optimal conditions (catalyst dosage = 0.2 g/L, pH = 5.8, and N-content of 5.14%), 93.8% of SMX degradation was obtained within 60 min. The plausible degradation products generation during the photocatalytic degradation of SMX was analyzed by LC-ESI/MS and the degradation pathway was proposed. In addition, the toxicity of the degradation products was investigated through Escherichia coli colony forming unit assay and a substantial biotoxicity reduction by this photodegradation was observed.

It has been established that 5-vinyl-substituted (N-R,N-vinylaminomethyl) isoxazolo(thiazolo, thiadiazolo)pyrimidines are formed when tetrahydropyrido[3, 4-d]pyrimidines, annelated with isoxazole, thiazole, and thiadiazole units are treated with terminal alkynes as a result of opening of the tetrahydropyridine ring. 7-Methoxymethyl-substituted [N-R,N-(dimethoxycarbonylvinyl)]aminoethyl- isoxazolo- and thiazolopyrimi-dines were obtained by reaction with dimethyl acetylenedicarboxylate (ADCE). Triazolo-pyrimidoazocine was obtained for the first time from tetrahydrotriazolopyrimidine and methyl propiolate.

Non-steroidal anti-inflammatory drugs are widely used therapeutic agents in the treatment of inflammation, pain and fever. Cyclooxygenase catalyzes the initial step of biotransformation of arachidonic acid to prostanoids, and exist as three distinct isozymes; COX-I, COX-II and COX-III. Selective COX-II inhibitors are a class of potential anti-inflammatory, analgesic, and antipyretic drugs with reduced gastrointestinal (GI) side effects compared to nonselective inhibitors. 3,4-Diarylisoxazole scaffold is recurrently found in a wide variety of NSAIDs, protein kinase inhibitors, hypertensive agents, and estrogen receptor (ER) modulators. In the present review, we document on the recent synthetic strategies of 3,4-diarylisoxazolyl scaffolds of valdecoxib and its relevant structural analogues.
