Beyond the tandem oxa-Michael strategy, an N-heterocyclic carbene-catalyzed kinetic resolution approach to access highly diastereo- and enantioenriched 2-aryl-3-nitro-chromane derivatives has been developed. An efficient strategy for the kinetic resolution of racemic 2-aryl-3-nitro-2H-chromenes was also successfully achieved. This catalytic kinetic resolution method allows the synthetically valuable chiral scaffolds, chromane and 2H-chromene, to be accessed in a single catalytic and asymmetric transformation, through the NHC-bound azolium homoenolate pathway.

A new triazole-functionalized tetracarboxylic acid ligand (H4L) has been synthesized and utilized for the fabrication of a 3D Zn-II organic framework with a Zn-4(-COO)(6) cluster as the secondary building unit. The framework exhibits very good thermal stability and consists of dual functionalities of exposed Lewis acidic metal sites and accessible nitrogen-donor Lewis basic sites. The Lewis basic nitrogen sites in the framework serve as CO2 binding sites for highly selective CO2 capture and the presence of exposed Lewis acidic metal sites in the framework make it an efficient heterogeneous catalyst for the chemical fixation of CO2 into value-added cyclic carbonates under ambient conditions.

Anthurium is an important ornamental crop in the world market and its floral scent can enhance its ornamental value. To date, studies of the components and formation mechanism of the floral scent of Anthurium are relatively few. In this study, the scent profiles of two Anthurium varieties were measured by gas chromatograph-mass spectrometer (GC-MS). There were 32 volatile organic compounds (VOCs) identified in Anthurium ‘Mystral’, and the most abundant compound was eucalyptol (57.5%). Extremely small amounts of VOCs were detected in Anthurium ‘Alabama’. Compared with A. ‘Alabama’, most genes related to floral scent synthesis exhibited a higher expression in A. ‘Mystral’, including AaDXS, AaDXR, AaMDS, AaHDS, AaTPS, AaDAHPS, AaADT2, AaPAL1, and AaPAL2. In order to produce new varieties of Anthurium with fragrance, 454 progenies of two crossbred combinations of A. ‘Mystral’ and A. ‘Alabama’ were obtained. Four F1 generation plants with different floral scent intensities were selected for further study. The major components of floral scent in the progenies were similar to that of the parental A. ‘Mystral’ plant. The expression patterns of genes related to floral scent synthesis were consistent with the relative contents of different types of VOCs. This study revealed the profiles of volatile compounds and associated gene expression in two Anthurium cultivars and their F1 hybrids, which provided a basis for the floral scent inheritance of Anthurium andraeanum.

The fruits of Zanthoxylum armatum DC. were collected from different altitudes (1000-2000 m) and populations (wild and cultivated) from Salyan district, Nepal. The essential oil was extracted by Clevenger apparatus and the components were analyzed through GC-MS. The yield of essential oil obtained from hydro-distillation of fruits ranged from 2.72 to 7.6%. The maximum yield was 7.6% from wild fruits at 1600-1800 m altitude and the minimum was 2.72% from cultivated fruits at 1000-1200 m altitude. This was the highest recorded essential oil yield from Z. armatum fruits. A total of 13 volatile compounds were identified from the essential oil by GC-MS analysis. The major components were linalool, cinnamate (E)methyl, limonene, myrcene, sabinene and terpinen-4-ol, which were present in higher proportion in all the samples. Other components were identified in a very low proportion. The main component linalool occurred in the highest proportion (74.12%) from wild populations at 1600-1800 m altitude and the lowest (44.73%) was from cultivated populations at 1000-1200 m altitude. The highest proportion of linalool was also reported for the first time in this study from Z. armatum fruits. Among the six major components of the essential oil, terpinen-4-ol was present in the lowest proportion. Results of the present study indicated that the altitude and habitat types could affect the essential oil composition in Zanthoxylum armatum fruits.

Many classical and emerging methodologies in organic chemistry rely on carbon dioxide (CO2) extrusion to generate reactive intermediates for bond-forming events. Synthetic reactions that involve the microscopic reverse-the carboxylation of reactive intermediates-have conventionally been undertaken using very different conditions. We report that chemically stable C(sp(3)) carboxylates, such as arylacetic acids and malonate half-esters, undergo uncatalyzed reversible decarboxylation in dimethylformamide solution. Decarboxylation-carboxylation occurs with substrates resistant to protodecarboxylation by Bronsted acids under otherwise identical conditions. Isotopically labeled carboxylic acids can be prepared in high chemical and isotopic yield by simply supplying an atmosphere of (CO2)-C-13 to carboxylate salts in polar aprotic solvents. An understanding of carboxylate reactivity in solution enables conditions for the trapping of aldehydes, ketones, and alpha,beta-unsaturated esters.

Comprehension in hemicellulose pyrolysis is critical to generate renewable fuel and valuable chemical. Herein, a self-designed tubular reactor was applied to observe the appearance alteration and chemical structure evolution during the whole xylan pyrolysis process. Before 200 degrees C, it was free moisture removal stage without significant chemical structure alteration. Xylan began to depolymerize at 200 degrees C corresponding with the appearance change from its original state to dark brown, cleavage of branched-chain and primary product acids & ketones generation. The main chain of xylan was completely broken at 250-350 degrees C via beta-1,4-glycosidic bond cleavage, dehydration, decarboxylation, and decarbonylation reaction. Acids were mainly originated from hemicellulose pyrolysis. The typical signals from FTIR,C-13 CP/MAS NMR were disappeared at 350 degrees C. In the carbonation stage, the C/H and C/O ratio reached 2.01 and 4.54, leading to the aromaticity enhancement of char and formation of carbon-centered radicals.

Ovarian cancer is associated with a high percentage of recurrence of tumors and resistance to chemotherapy. Cancer stem cells (CSCs) are responsible for cancer progression, tumor recurrence, metastasis, and chemoresistance. Thus, developing CSC-targeting therapy is an urgent need in cancer research and clinical application. In an attempt to achieve potent and selective anti-CSC agents, a series of celastrol derivatives with cinnamamide chains were synthesized and evaluated for their anti-ovarian cancer activities. Most of the compounds exhibited stronger antiproliferative activity than celastrol, and celastrol derivative 7g with a 3,4,5-trimethoxycinnamamide side chain was found to be the most potent antiproliferative agent against ovarian cancer cells with an IC50 value of 0.6 mu M. Additionally, compound 7g significantly inhibited the colony formation ability and reduced the number of tumor spheres. Furthermore, compound 7g decreased the percentage of CD44(+), CD133(+) and ALDH(+) cells. Thus, compound 7g is a promising anti-CSC agent and could serve as a candidate for the development of new antiovarian cancer drugs. (C) 2019 Elsevier Masson SAS. All rights reserved.

Aims We sought to examine sex differences in congestion in patients hospitalized for acute heart failure (AHF). Understanding congestive patterns in women and men with AHF may provide insights into sex differences in the presentation and prognosis of AHF patients. Methods and results In a prospective, two-site study in adults hospitalized for AHF, four-zone lung ultrasound (LUS) was performed at the time of echocardiography at baseline (LUS1) and, in a subset, pre-discharge (LUS2). B-lines on LUS and echocardiographic images were analysed offline, blinded to clinical information and outcomes. Among 349 patients with LUS1 data (median age 74, 59% male, and 87% White), women had higher left ventricular ejection fraction (mean 43% vs. 36%, P < 0.001), higher tricuspid annular plane systolic excursion (mean 17 vs. 15 mm, P = 0.021), and higher measures of filling pressures (median E/e' 20 vs. 16, P < 0.001). B-line number on LUS1 (median 6 vs. 6, P = 0.69) and admission N-terminal pro-B-type natriuretic peptide levels (median 3932 vs. 3483 pg/ml, P = 0.77) were similar in women and men. In 121 patients with both LUS1 and LUS2 data, there was a similar and significant decrease in B-lines from baseline to discharge in both women and men. The risk of the composite 90 day outcome increased with higher B-line number on four-zone LUS2: unadjusted hazard ratio for each B-line tertile was 1.86 (95% confidence interval 1.08-3.20, P = 0.025) in women and 1.65 (95% confidence interval 1.03-2.64, P = 0.037) in men (interaction P = 0.72). Conclusions Among patients with AHF, echocardiographic markers differed between women and men at baseline, whereas B-line number on LUS did not. The dynamic changes in B-lines during a hospitalization for AHF were similar in women and men. Formula: C10H10O2.
