A benzene-free synthesis of multisubstituted catechol via an oxidative dearomatic reorganization is reported. This reaction tolerated a wide spectrum of functionalities, which could be applied in the synthesis of an electron-deficient arene-conjugated catechol that is difficult to access via biomimetic oxidative coupling. In addition, a diversification-oriented transformation that leveraged the versatile catechol afforded a series of functionality-rich products.

A divergent efficient assembly of disubstituted 1,2,4-triazoles was established by cyclization of readily accessible N’-nitro-2-hydrocarbylidene-hydrazinecarboximidamides with moderate to excellent yields under mild reaction conditions. This divergent synthetic strategy was achieved simply by varying the reaction conditions. Under acidic conditions, amino-1,2,4-triazoles were obtained by an intramolecular redox reaction involving the NO2 group. Control experiments and DFT studies revealed that this transformation proceeds via an intramolecular 1,3-hydride transfer pathway leading to HNO2 elimination. Under neutral conditions with water as the solvent, nitroimino-1,2,4-triazoles were obtained by oxidative intramolecular annulation under air.

Saw the article Kinetic study on aminolysis of aryl X-substituted-cinnamates in acetonitrile: differential medium effect determines reactivity and reaction mechanism published in 2019.0, Reprint Addresses Um, IH (corresponding author), Ewha Womans Univ, Dept Chem & Nano Sci, Seoul 120750, South Korea.; Dust, JM (corresponding author), Grenfell Campus Mem Univ Newfoundland, Dept Chem, Corner Brook, NF A2H 5G4, Canada.; Dust, JM (corresponding author), Grenfell Campus Mem Univ Newfoundland, Dept Environm Sci, Corner Brook, NF A2H 5G4, Canada..

A kinetic study on nucleophilic substitution reactions of 2,4-dinitrophenyl X-substituted-cinnamates (1a-1f) and Y-substituted-phenyl cinnamates (2a-2g) with a series of alicyclic secondary amines in MeCN at 25.0 +/- 0.1 degrees C is reported. The Bronsted-type plots for the reactions of 1a-1f are linear with beta(nuc) = 0.47 similar to 0.50, indicating that the bond formation between the amine nucleophile and the electrophilic center is advanced slightly in the transition state. The Bronsted-type plot for the reactions of 2a-2g with piperidine is also linear with beta(1g) = -0.66, which is a typical beta(1g) value for reactions reported previously to proceed through a concerted mechanism. Furthermore, the Hammett plot correlated with sigma-constants results in much better linearity than that correlated with sigma degrees constants, implying that expulsion of the leaving group is advanced in the rate-determining step (RDS). Thus, the reactions are concluded to proceed through a concerted mechanism. The Hammett plots for the reactions of 1a-1f consist of two intersecting straight lines, whereas the corresponding Yukawa-Tsuno plots exhibit excellent linear correlations with rho(X) = 0.62 similar to 0.71 and r = 0.65 similar to 0.68. Apparently, the nonlinear Hammett plots are not due to a change in the reaction mechanism (or the RDS) but are caused by stabilization of the substrate possessing an electron-donating group (EDG) in the cinnamoyl moiety through resonance interactions between the EDG and the C=O bond of the substrate. Medium effects on reactivity and reaction mechanism are also discussed.

A series of seven new (1, 3, 6, 7, 10, 12, and 13) and six (2, 4, 5, 8, 9, and 11) known diarylpentanoid analogs were synthesized and assessed for their nitric oxide (NO) and alpha-glucosidase inhibitory activities as well as their antioxidant capacity. Nine compounds (2, 3, 4, 5, 6, 8, 11, 12, and 13) were found to exhibit comparable activity to that of curcumin (IC50 = 13.0 mu M), in which compound 8 has displayed strongest NO inhibitory activity with the IC50 values of 17.5 mu M. Meanwhile, four compounds (1, 7, 12, and 13) were found to possess better alpha-glucosidase inhibitory activity than that of curcumin (30.9 mu M), with the IC50 values ranging from 19.4 to 24.9 mu M. On the other hand, none of the synthesized compounds has achieved better DPPH scavenging activities than that of curcumin, indicating the relatively poor antioxidant potential of desired diarylpentanoid structure. Structure-activity relationship (SAR) study disclosed that the existence of meta-hydroxyphenyl and bromo groups is crucial for antiinflammatory and anti-alpha-glucosidase activities, respectively. Molecular docking study showed that bromo moiety could form additional hydrophobic contacts with alpha-glucosidase, thereby increased the inhibition of diarylpentanoid against alpha-glucosidase. The overall results suggested that diarylpentanoids with poly-meta-hydroxylated phenyl ring and multiple bromo groups may lead to the discovery of new diarylpentanoids with both antiinflammatory and anti-alpha-glucosidase activities.

Conventional detection and identification of the fungi causing postharvest diseases in fruits are time-consuming, laborious, and can only be performed after the manifestation of symptoms. In this work, an alternative method based on headspace analysis, and which allows the early detection of fungi species frequently found papaya fruit, is presented. Volatile compounds of four in vitro fungi cultures (Alternaria alternata, Colletotrichum gloeosporioides, Fusarium solani, and Lasiodiplodia theobromae) were extracted using solid-phase microextraction (SPME) and analyzed by gas chromatography coupled with mass spectrometry. The resulting chromatographic fingerprints were explored by conventional principal component analysis (PCA) and analysis of variance (ANOVA)-PCA. Decomposition of the original matrix, according to the factors proposed in the experimental design, by ANOVA before applying the PCA improved the distinction of the control and fungi samples. The main chromatographic peaks referring to the metabolites produced by each species were successfully identified using the proposed analysis. A primary alcohol with five carbons and phenylethyl alcohol were observed in all fungi species and so could be used as an indicative of postharvest disease. Although unique metabolites were detected for all fungi species, only those from C. gloeosporioides and another from F. solani could be surely identified, such as thymolmethyl and 3,6-dimethylhept-6-en-4-yn-3-ol, respectively. The in vitro results obtained are promising, and it is expected that the biomarkers detected in this work will be useful in future development of methods for the early detection and classification of papaya fungi species.

The selective N-alkylation of anilines with benzylic alcohols can be switched in favor of the dehydrogenative condensation process using the nitrile-ligated Knolker’s complex by conducting the reaction either in a closed system under inert conditions, or in an open system in air. The selective formation of imines, containing reactive C=N bonds, provides an opportunity towards further functionalization. Indeed, a one-pot three-component condensation of alcohols, amines and phosphites, promoted by an iron-based Knolker-type complex in combination with a chiral BINOL-based phosphoric acid, provides access to enantioenriched -N-alkylaminophosphonates.

Pyrrolizidine alkaloids (PAs) are genotoxic carcinogenic phytotoxins mostly prevalent in the Boraginaceae, Asteraceae and Fabaceae families. Heliotropium species (Boraginaceae) are PA-producing weeds, widely distributed in the Mediterranean region, that have been implicated with lethal intoxications in livestock and humans. In Israel, H. europaeum, H. rotundifolium and H. suaveolens are the most prevalent species. The toxicity of PA-producing plants depends on the PA concentration and composition. PAs occur in plants as mixtures of dozens of various PA congeners. Hence, the risk arising from simultaneous exposure to different congeners has to be evaluated. The comparative risk evaluation of the three Heliotropium species was based on recently proposed interim relative potency (iREP) factors, which take into account certain structural features as well as in vitro and in vivo toxicity data obtained for several PAs of different classes. The aim of the present study was to determine the PA profile of the major organ parts of H. europaeum, H. rotundifolium and H. suaveolens in order to assess the plants’ relative toxic potential by utilizing the iREP concept. In total, 31 different PAs were found, among which 20 PAs were described for the first time for H. rotundifolium and H. suaveolens. The most prominent PAs were heliotrine-N-oxide, europine-N-oxide and lasiocarpine-N-oxide. Europine-N-oxide displayed significant differences among the three species. The PA levels ranged between 0.5 and 5% of the dry weight. The flowers of the three species were rich in PAs, while the PA content in the root and flowers of H. europaeum was higher than that of the other species. H. europaeum was found to pose a higher risk to mammals than H. rotundifolium, whereas no differences were found between H. europaeum and H. suaveolens as well as H. suaveolens and H. rotundifolium.
