The addition of pi-allylmetal complexes to carbonyls is the most important route to homoallylic alcohols. This study reports the first photocatalytic generation of pi-allyltitanium complexes by a radical strategy. This novel strategy enables the three-component allylation of carbonyls with 1,3-butadiene, providing rapid access to valuable homoallylic alcohols (over 60 examples). The exceptional regio- and diastereoselectivity provided by dual photoredox/Ti catalysis is comparable to that of the Cr-catalyzed Nozaki-Hiyama-Kishi allylation reaction.

Bimetallic silver and copper incorporated mesoporous MCM-48 (Ag/CuO/MCM-48) was synthesized by simple wet-impregnation method. The knowledge about its structural properties was gathered by means of Fourier transform-infrared, energy-dispersive X-ray, X-ray diffraction, field emission-scanning electron microscopy, transmission electron microscopy and Brunauer-Emmett-Teller analyses. The catalytic activity of Ag/CuO/MCM-48 was examined in the one-pot three-component reaction of 3-(1-methyl-1H-pyrrol-2-yl)-3-oxopropanenitrile, malononitrile and various aromatic aldehydes leading to novel pyran-pyrrole hybrid derivatives in reduced reaction times (5-10 min) and excellent yields (88-97%). Application of Ag/CuO/MCM-48 as a potent heterogeneous catalyst with good reusability up to five times, use of ethanol as an eco-compatible medium and chromatography-free work-up are some crucial green aspects of this procedure.

Novel 1-(1-benzoylpiperidin-4-yl)methanamine derivatives with high affinity and selectivity for serotonin 5-HT1A receptors were obtained and tested in four functional assays: ERK1/2 phosphorylation, adenylyl cyclase inhibition, calcium mobilization, and beta-arrestin recruitment. Compounds 44 and 56 (2-methylaminophenoxyethyl and 2-(1H-indol-4-yloxy)ethyl derivatives, respectively) were selected as biased agonists with highly differential signaling fingerprints that translated into distinct in vivo profiles. In vitro, 44 showed biased agonism for ERK1/2 phosphorylation and, in vivo, it preferentially exerted an antidepressant-like effect in the Porsolt forced swimming test in rats. In contrast, compound 56 exhibited a first-in-class profile: it preferentially and potently activated beta-arrestin recruitment in vitro and potently elicited lower lip retraction in vivo, a component of serotonergic syndrome. Both compounds showed promising developability properties. The presented 5-HT1A receptor-biased agonists, preferentially targeting various signaling pathways, have the potential to become drug candidates for distinct central nervous system pathologies and possessing accentuated therapeutic activity and reduced side effects.

In this study, the aroma components of bead-shaped green teas were compared through headspace solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry/olfactometry (GC-MS/O) coupled with chemometrics. A total of 62 volatile compounds were identified in 16 green tea samples. Notably, comparison of GC-MS/O and odour activity values (OAV) results revealed that nonanal, decanal, (E)-2-nonenal, beta-ionone, and 1-octen-3-one were the most powerful aroma-active compounds that contributed to the aroma profile of the bead-shaped green teas. Furthermore, multivariate statistical techniques (such as principal component analysis, partial least squares-discriminant analysis, and hierarchical cluster analysis) were used to characterise the bead-shaped green teas according to their geographical origin and the flavour characteristics of their volatile compounds. Additionally, the variable importance in the projection method was used to identify 20 volatile markers that could successfully distinguish bead-shaped green teas on the basis of three flavour characteristics. The results of the analysis revealed that HS-SPME and GC-MS/O coupled with chemometrics can provide an effective method for characterising and classifying bead-shaped green teas.

The spiced beef is exposed to the invading of spoilage bacteria including Listeria monocytogenes. In the present study, the antimicrobial effects against L. monocytogenes of the chitosan (CS) films incorporated with apricot (Prunus armeniaca) kernel essential oil (AKEO) at 0.5% and 1.0% were demonstrated in solid medium, micro-atmosphere, liquidmedia and spiced beef. In the refrigerated storage for 24 days at 4 degrees C, compared with the control sample, the levels of peroxide value (PV) and thiobarbituric acid (TBA) of the spiced beef packed by CS films incorporated AKEO at 0.5% and 1.0% were decreased to 4.8 and 3.6 meq peroxide/kg, and 0.5 and 0.4 mg MDA/kg (p < 0.5 or p < 0.1), and the levels for pH and total carbonyls (TC) were decreased to 5.8 and 5.7, and 0.7 and 0.6 nmol/mg protein (p < 0.5 or p < 0.1) on the 24th day, respectively. Furthermore, the sensory evaluation exhibited that the spiced beef packed by CS films incorporated AKEO at 1.0% had better sensory attributes including taste, color, texture and overall acceptance during the whole storage period. Consequently, CS films incorporated AKEO at 1.0% can be developed to be one packaging material for spiced beef. (C) 2020 Elsevier B.V. All rights reserved. SDS of cas: 100-51-6.

Zn(OAc)(2)-mediated Mannich-type reaction was studied for the synthesis of 3,3′-pyrrolidinyl-spirooxindole from L-2,3-dihydro-2-oxotryptophan methyl ester and aldehydes. The study indicates that the Mannich-type spirocyclization is significantly influenced by both the cation and anion of the metal salt, base, stoichiometry, stereoelectronics of aldehyde and temperature. With the enhancement by Zn(OAc)(2), the substrate induced asymmetric reaction works on both aromatic and aliphatic aldehydes but at different temperatures. It could deliver the (2’S,3R,5’S)-pyrrodinyl-spirooxindole with up to 96% of diastereomeric ratio in good yield under optimized conditions. (C) 2021 Elsevier Ltd. All rights reserved.

Transition metal-catalyzed skeletal rearrangement reactions have rapid advances in organic community. Their development benefits synthetic methodologies by providing versatile and flexible approaches toward special molecular scaffolds with high selectivity. Herein, a gold-catalyzed skeletal rearrangement of alkenes with alkynyl bromides is reported, enabling direct and regioselective generation of more than 50 examples of skeletally diverse tricyclic heterocycles, namely, syn-tetrahydrocyclopenta[b]indoles and benzofuro[3,2-b]pyridines, with generally good yields. This protocol could tolerate terminal unactivated and internal activated alkenes under air conditions, which is hitherto unreported in gold catalysis and scarcely realized by other metal-catalyzed reactions, thus opening avenues for the regioselective assembly of heterocyclic systems with high efficiency. Aside from examining the scope of this skeletal rearrangement, mechanistic investigations to explain the regioselectivity of forming syn-tetrahydrocyclopenta[b]indoles and benzofuro[3,2-b]pyridines were conducted by systematic theoretical calculations.

Several flexible and rigid analogs of 4H-1,2,4-triazoles (compounds 8a-g and 9a-g) bearing trimethoxyphenyl pharmacophoric unit, were designed and synthesized as potential anticancer agents. The in vitro cytotoxic assay indicated that both flexible and rigid analogs (8 and 9, respectively) can potentially inhibit the growth of cancerous cells (A549, MCF7, and SKOV3), with IC50 values less than 5.0 mu M. Furthermore, compounds 10a-l as regional isomers of compounds 9 exhibited remarkable cytotoxic activity with IC50 values ranging from 0.30 to 5.0 mu M. The rigid analogs 9a, 10h and 10k were significantly more potent than etoposide against MCF7, SKOV3 and A549 cells, respectively. These compounds showed high selectivity towards cancer cells over normal cells, as they had no significant cytotoxicity against L929 cells. In addition, the representative compounds 9a and 10h could inhibit the tubulin polymerization at micro-molar levels. By determining changes in the colchicine-tubulin fluorescence, it was suggested that compound 10h could bind to the tubulin at the colchicine pocket. The molecular docking study further confirmed the inhibitory activity of promising compounds 9a, 10h and 10k on tubulin polymerization through binding to the colchicine-binding site.
