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.

Herein we report the multicomponent synthesis of the bis(indolyl)methane derivatives in a ball mill. The reaction was carried out under solvent-free conditions using only the Lewis acid-surfactant-SiO2 composite nanocatalyst (LASSC) prepared in situ. The unsymmetrical bis(indolyl) methane derivatives containing nitro or fluorine substitution with a yield of 72%-92% were obtained in a short reaction time. Within we verified that under the action of the combined catalyst of AlCl3 center dot 6H(2)O + SDS + SiO2, the method of preparing unsymmetrical bis(indolyl)methane by mechanical grinding without solvent has obvious advantages. Finally, we inspected that the catalysis system can be used eight times without a significant decrease in activity.

Silyl-substituted ketenes are attractive molecular building blocks due to their stability and ease of storage, as opposed to unstable alkyl and aryl ketenes. To better understand the reactivity of silyl ketenes and, in turn, their use in the preparation of highly functionalized small molecules, the reaction of silyl ketenes with different nucleophiles was studied. The addition of alcohol, amine, or thiol nucleophiles to the central carbon of silyl ketene, followed by proton transfer afforded alpha-silyl ester, amide, or thio-ester, respectively. Catalytic amounts of Lewis acid greatly increase the rate of the reaction, and the impact of nucleophile, Lewis acid, and silyl substituent are evaluated. The small molecules produced from these reactions give insight into the use of silyl ketenes as building blocks for complex molecular structures.

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.

Keto piperazines and aminocoumarins are privileged building blocks for the construction of geometrically constrained peptides and therefore valuable structures in drug discovery. Combining these two heterocycles provides unique rigid polycyclic peptidomimetics with drug-like properties including many points of diversity that could be modulated to interact with different biological receptors. This work describes an efficient multicomponent approach to condensed chromenopiperazines based on the novel enol-Ugi reaction. Importantly, this strategy involves the first reported post-condensation transformation of an enol-Ugi adduct.

An approach to preparing enynyl-aryl ethers from phenols and phenylacetylenes is described. This method without extra ligands, overcoming the favored Glaser-Hay dimerization of alkyne, features a wide substrate scope (38 examples including endofolliculina and indole) and the merits of high atom and step economy, good regio- and stereoselectivity (Z-isomers major) in moderate to good isolated yields. Mechanistic studies show that the reaction is enabled by distinctive copper/iodide tandem catalysis.

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.
