The present work describes the preparation of two ionic liquid and carboxyl acid silane reagents via photo-initiated thiol-ene click chemistry that have been bonded to silica to afford two mixed-mode stationary phases (Sil-C4Im-C9Co and Sil-C9Im-C4Co). The two stationary phases provided satisfactory retention repeatability and efficiencies. The influence of acetonitrile content, salt concentration and pH of the mobile phase was investigated to clarify the retention properties of the prepared stationary phases. The results showed that the prepared Sil-C4Im-C9Co and Sil-C9Im-C4Co undergo multiple interactions with solutes under different chromatographic conditions. The retention mechanisms were further studied by the linear energy solvation relationship and Van’t Hoff plots. Finally, the stationary phases were employed to separate hydrophobic solutes (alkylbenzenes and polycyclic aromatic hydrocarbons) under reversed phase liquid chromatography (RPLC) mode, hydrophilic solutes (carboxylic acids, nucleosides and bases) under hydrophilic interaction liquid chromatography (HILIC) mode and inorganic anions under ion-exchange chromatography (IEC) mode, providing excellent performance and varying selectivity when compared with a commercial column. The bonding method in this work is feasible and the prepared stationary phases are promising when employed in RPLC/HILIC/IEC mixed-mode chromatography applications. (C) 2019 Elsevier B.V.

A site-selective supported palladium nanoparticle catalyzed Suzuki-Miyaura cross-coupling reaction with heteroaryl esters and arylboronic acids as coupling partners was developed. This methodology provides a heterogeneous catalytic route for aryl ketone formation via C(acyl)-O bond activation of esters by successful suppression of the undesired decarbonylation phenomenon. The catalyst can be reused and shows high activity after eight cycles. The XPS analysis of the catalyst before and after the reaction suggested that the reaction might be performed via a Pd-0/Pd-II catalytic cycle that began with Pd-0.

A covalent hybrid of halloysite-poly(methyl methacrylate-co-maleic anhydride) was prepared and applied for the immobilization of Pd nanoparticles. The hybrid system, Pd@Hal-Gua-Poly, was then characterized via TEM, TGA, ICP, BET, FTIR and XRD and successfully used as a heterogeneous catalyst for promoting two main Pd-catalyzed reactions, i.e. hydrogenation of nitro-arenes and Suzuki coupling reaction under mild and eco-friendly conditions. The study of recyclability of the catalyst confirmed high recyclability and low Pd leaching of Pd@Hal-Gua-Poly. Moreover, the hot-filtration test showed the heterogeneous nature of the catalysts. Notably, the comparison of the activity of the catalyst with that of Pd@Hal and Pd@Poly confirmed the superior catalytic activity of the former, indicating that the hybridization of Hal and Poly could lead to the improvement of the catalytic activity.

We describe the synthesis of 10-aza-9-oxakalkitoxin, an N,N,O-trisubstituted hydroxylamine-based analog, or hydroxalog, of the cytotoxic marine natural product kalkitoxin in which the -NMe-O- moiety replaces a -CHMe-CH2- unit in the backbone of the natural product. 10-Aza-9-oxakalkitoxin displays potent and selective cytotoxicity (IC50 2.4 ng mL(-1)) comparable to that of kalkitoxin itself (IC50 3.2 ng mL(-1)) against the human hepato-carcinoma cell line HepG2 over both the human leukemia cell line CEM and the normal hematopoietic CFU-GM. Like kalkitoxin, and contrary to the common expectation for hydroxylamines, 10-aza-9-oxakalkitoxin is not mutagenic.

The first asymmetric Pd-II-catalyzed aminofluorination of unactivated alkenes using chiral quinoline-oxazolines (Quox) as ligands has been developed. This reaction provides easy access to a wide array of enantiomerically enriched beta-fluoropiperidines in good yields and with excellent enantioselectivity. Notably, Et4NF.3 HF as a readily accessible nucleophilic fluoride source was found to play an essential role in the enantioselective control, and CsOCF3 also acts a key additive to improve the excellent ee value of products.

A catalyst-free and solvent-free method for the hydroboration of a variety of carboxylic acids with pinacolborane was developed. The hydroboration of various aromatic and aliphatic carboxylic acids as well as dicarboxylic acids with HBpin could be completed within 6 h at room temperature or within 1 h at 60 degrees C to give the products in quantitative yields under neat conditions without the need for any solvent or metal catalyst. The possible reaction mechanism was investigated in detail based on the corresponding DFT calculations and the stoichiometric reaction of acetic acid with different equivalents of HBpin (at room temperature and 0 degrees C) and it revealed the stepwise nature of the protocol.

A copper-mediated oxidative C-H/N-H annulation of aromatic amides with dialkyl malonates has been presented to afford synthetically valuable dihydrobenzoindoles and isoindolinones. The reaction proceeds through direct oxidative C(sp(2))H/C(sp(3))-H coupling followed by an intramolecular N-H/C(sp(3))-H dehydrogenative coupling to deliver the target motifs with broad scope and functional group tolerance.

In patients with diabetes mellitus (DM), amputation rates exceed 30% when lower extremity osteomyelitis is present. We sought to determine the rate of osteomyelitis and any subsequent amputation in our patients with DM and lower extremity burns. We performed a single-site, retrospective review at our burn center using the institutional burn center registry, linked to clinical and administrative data. Adults (>= 18 years old) with DM admitted from January 1, 2014 to December 31, 2018 for isolated lower extremity burns were eligible for inclusion. We evaluated demographics, burn characteristics, comorbidities, presence of radiologically confirmed osteomyelitis, length of stay (LOS), inpatient hospitalization costs, and amputation rate at 3 months and 12 months after injury. We identified 103 patients with DM and isolated lower extremity burns. Of these, 88 patients did not have osteomyelitis, while 15 patients had radiologically confirmed osteomyelitis within 3 months of the burn injury. Compared to patients without osteomyelitis, patients with osteomyelitis had significantly increased LOS (average LOS 22.7 days vs 12.1 days, P = .0042), inpatient hospitalization costs (average $135,345 vs $62,237, P = .0008), amputation rate within 3 months (66.7% vs 5.70%, P < .00001), and amputation rate within 12 months (66.7% vs 9.1%, P < .0001). The two groups were otherwise similar in demographics, burn injury characteristics, access to healthcare, and preexisting comorbidities. Patients with DM and lower extremity burns incurred increased LOS, higher inpatient hospitalization costs, and increased amputation rates if radiologically confirmed osteomyelitis was present within 3 months of the burn injury.
