The floral scents of three forms of cultivated Plumeria rubra L. were evaluated through mass flowering phenology using the dynamic headspace adsorption method and were identified with coupled gas chromatography and mass spectrometry. The forms P. rubra f. acutifolia and P. rubra f. lutea had white and yellow flower petals, respectively, and the flower petals of P. rubra f. rubra were red. Although 68 components of the flower scents of the three forms were recorded in different proportions, only 14 chemical compounds were identified with statistically significance. The main volatile compounds in the red form of P. rubra L. were fatty acid derivatives (56.75%). The main compounds in the white and yellow forms of P. rubra L. were benzenoid and terpene, with proportions of 48.38% and 33.33% in P. rubra f. acutifolia and proportions of 42.30% and 47.43% in P. rubra f. lutea, respectively. These differences in the flower scents might be one result of the minor genetic differences between these forms, similar to the role of genetic differences in the flower color combinations of the three forms. We conclude that petal color traits can, to some extent, reflect differences in floral scent compositions and that minor genetic differences of different plant forms exert impacts not only on flower color but also on the phytochemistry of floral scents.

We report herein a Lewis acid-catalyzed nucleophilic double-addition of indoles to ketones under mild conditions. This process occurs with various ketones ranging from dialkyl ketones to diaryl ketones, thereby providing access to an array of bis(indolyl)methanes bearing all-carbon quaternary centers, including tetra-aryl carbon centers. The products can be transformed into bis(indole)-fused polycyclics and bis(indolyl)alkenes.

A single and accessible cationic iridium(III)metallacycle effectively catalyzes the one-pot sequential double hydrosilylation of challenging alpha,beta-unsaturated secondary and tertiary amides to afford, in a controlled and straightforward way, the corresponding reduced products, namely, the related secondary and tertiary amides and amines. The catalytic hydrosilylations of the conjugated amides described herein proceeded in good yields and high chemoselectivities. The critical silyl enolate, in other words silyl ketene aminal intermediate, has been observed and characterized by using control experiments, mass spectrometry and state of the art NMR analyses. The present achievements indicate a promising potential of catalysts based on metallacycles for future significant developments in one-pot multicatalytic synthesis and therefore the production of highly functionalized and complex organic molecules.

New linkages for covalent organic frameworks (COFs) have been continuously pursued by chemists as they serve as the structure and property foundation for the materials. Developing new reaction types or modifying known linkages have been the only two methods to create new COF linkages. Herein, we report a novel strategy that uses H3PO3 as a bifunctional catalyst to achieve amine-linked COFs from readily available amine and aldehyde linkers. The acidic proton of H3PO3 catalyzes the imine framework formation, which is then in situ reduced to the amine COF by the reductive P-H moiety. The amine-linked COF outperforms its imine analogue in promoting Knoevenagel condensation because of the more basic sites and higher stability.

In this paper, 21 naphthalene-chalcone derivatives were synthesized and their biological effects were evaluated. The results showed that compounds 2a-2u displayed clear antidepressant activity at 30 mg/kg in the forced swimming test. Compounds 2h, 2o, 2t, and 2u exhibited a good antidepressant effect in the forced swimming test and tail suspension test at 30 mg/kg. Compounds 2h, 2o, 2t, and 2u but had no effect on locomotor activity in the open-field test in mice. In addition, the most antidepressant activity of compound 2o is likely mediated by increased serotonin and norepinephrine levels in central nervous system. Compounds 2a-2u also showed the analgesic and anti-inflammatory effects at 30 mg/kg.

This paper describes the synthesis of polyindole by chemical oxidative polymerization using copper chloride as oxidant. Polyindole was characterized by various spectroscopic techniques like FT-IR, XRD, FESEM, and TGA. The XRD pattern confirms the semi-crystalline nature of polyindole. An efficient, solvent-free, ultrasound-assisted synthesis of biologically active 3,4-dihydropyrimidin-2(1 H)-one/thiones (DHPM) derivatives is reported by using polyindole as a recyclable catalyst. The advantages of this method are mild reaction conditions, short reaction time, excellent yields with high purity and low loading of catalyst. Polyindole can be used several times without loss of significant catalytic activity as compared to the other reported catalysts. Factors affecting on the rate of reaction, like use of ultrasonication, temperature, solvent, amount, and recyclability of catalyst have also been studied.

Three series of sulfonate derivatives of paeonol were synthesized and screened in vitro for their anti-oomycete activity against P. capsici, respectively. Among all the compounds, 4m displayed the best promising and pronounced anti-oomycete activity against P. capsici than zoxamide, with the EC50 values of 24.51 and 26.87 mg/L, respectively. The results show that acetyl and 4-OCH3 are two necessary groups. The existence of these two sites is closely related to the anti-oomycete activity. Relatively speaking, hydroxyl group is well tolerated, and the results showed that after modification of hydroxyl group with sulfonyl, the anti-oomycete activity was significantly increased.

A mesoporous Mn1Zr0.5Oy solid solution is prepared with a template-free co-precipitation method and is used as an efficient heterogeneous catalyst for oxidative coupling of benzyl alcohol and aniline in the absence of base under mild conditions. XRD, XPS, N-2 physisorption, H-2-TPR, O-2-TPD, NH3-TPD and CO2-TPD were used to study the influence of calcination temperature on the structure, redox properties, acidity-basicity, as well as the catalytic behaviors of the Mn1Zr0.5Oy catalyst. The results show that the optimal catalyst calcined at 400 degrees C displays the highest specific surface area (228 m(2) g(-1)), highest fraction of unsaturated Mn3+ ions (45.4 %) and reactive O-surf. species (52.5 %), and the highest acidity (1.06 mmol g(-1)) and basicity (0.48 mmol g(-1)). Thereby, an enhanced benzylideneaniline formation (5.50 mmol g(cat)(-1) h(-1)) based on a 99 % yield is obtained at 80 degrees C under air atmosphere. This is one of the top results ever reported for all the Mn-based catalysts. The structure-activity relation is finally discussed.

Annulation of alpha,beta-unsaturated amides with electrondeficient 1,3-dienes gave 5,6-dihydropyridin-2(1H)-ones in the presence of a hydroxoiridium catalyst. The reaction proceeded via direct C-H alkylation of acrylamides with conjugated dienes, followed by intramolecular aza-Michael addition, thus giving dihydropyridinones stereoselectively in good yields.

In this study, novel quinazolinone derivatives 7a-n were synthesized and evaluated against metabolic enzymes including alpha-glycosidase, acetylcholinesterase, butyrylcholinesterase, human carbonic anhydrase I, and II. These compounds exhibited high inhibitory activities in comparison to used standard inhibitors with K-i values in the range of 19.28-135.88 nM for alpha-glycosidase (K-i value for standard inhibitor = 187.71 nM), 0.68-23.01 nM for acetylcholinesterase (K-i value for standard inhibitor = 53.31 nM), 1.01-29.56 nM for butyrylcholinesterase (K-i value for standard inhibitor = 58.16 nM), 10.25-126.05 nM for human carbonic anhydrase I (K-i value for standard inhibitor = 248.18 nM), and 13.46-178.35 nM for human carbonic anhydrase II (K-i value for standard inhibitor = 323.72). Furthermore, the most potent compounds against each enzyme were selected in order to evaluate interaction modes of these compounds in the active site of the target enzyme. Cytotoxicity assay of the title compounds 7a-n against cancer cell lines MCF-7 and LNCaP demonstrated that these compounds do not show significant cytotoxic effects.
