The current study evaluated the key characters of aroma composition in diversified red wines (Cinsaut, Grenache, Cabernet Franc, Petit Verdot, Cabernet Sauvignon, Nielluccio, Tempranillo, Syrah, Merlot and Caladoc). Out of hundreds of volatile compounds 64 compounds were considered for study. Different groups consisting of fatty acids, volatile alcohols, aldehydes, esters, volatile phenols and terpenes were analysed using gas chromatography mass spectrometry coupled with thermal desorption (TD-GC-MS). Among all these diversified classes, alcohols were found as the most dominant group followed by esters and acids whereas aldehydes, phenols and terpenes were found to be minor compounds. Among the varieties, Nielluccio wine recorded highest concentration of total volatile compounds (191.53 mg/L) while, it was least in Caladoc wines (15.45 mg/L). The principal component analysis clearly differentiated Grenache wines based on their relationships between scores and their aroma composition followed by Nielluccio and Cinsuat wines. Out of sixty four compounds, only six aromatic compounds viz. butanediol, isoamyl actate, gamma-Terpene, butanol, acetic acid and furfural have satisfying aroma descriptors with floral and fruity nuances and contribute to differentiate the Grenache wines from other varieties which have similar scores in PC1 analysis. The cluster analysis also suggested that the wines in the same group (Cinsaut, Tempranillo and Syrah), (Cabernet Franc, Cabernet Sauvignon, Caladoc and Merlot) and (Nielluccio and Petit Verdot) had similar aroma characterization. Grenache wines were well differentiated from the sub group formed by other red varieties.

Lipid migration is widespread in food system and has an important effect on food quality. It is urgent to explore the lipid migration in egg yolk after heating. The content of lipids in upper part (HL) was higher than that in bottom part (LL), and the lipids migration in yolk gel under heating were confirmed by MRI (T1) and T2 relaxation time of LF-NMR. Subsequently, the XDR result demonstrated the high lipid content induced the decrease in crystallinity of protein in HL part. The structures of HL part trend to be more ordered, stable (beta-sheet & beta-turns) and flat (alpha-helices) than LL part, also, more water distributed in LL part were observed by FTIR spectrum. The SEM results revealed that lipids migrated from LL to HL part, eventually lead to the protein in HL part of heated yolk gel unfold, the globular structure collapsed and become flatter. Morever, ethyl acetate, hexanal, etc. and hexanal, ethyl acetate, dimethyl-silanediol, etc. were identified as the main VOCs of LL and HL part of heated yolk gel, respectively. Lipid migration result in more lipid-specific volatiles were formed in the HL part, such as hexanal, 3-hydroxy-cyclohexanone, 2-pentyl-furan, D-limonene, 2-ethyl-1-hexanol, benzeneacetaldehyde. Lipid migration in heated yolk gel, caused by heat treatment, resulted in the changes of structure and flavor between HL and LL part.

N-Acylpyrrole-type amides are a class of versatile building blocks in asymmetric synthesis. We report that by employing Ni(COD)(2)/2,2 ‘-bipyridine (5 mol%) catalytic system, the direct, catalytic alcoholysis of N-acylpyrrole-type aromatic and aliphatic amides with both primary and secondary alcohols can be achieved efficiently under very mild conditions (rt, 1 h) even at gram scale. By increasing the catalyst loading to 10 mol%, prolonging reaction time (18 h), and/or elevating reaction temperature to 50 degrees C/80 degrees C, the reaction could be extended to both complex and hindered N-acylpyrroles as well as to N-acylpyrazoles, Nacylindoles, and to other (functionalized) primary and secondary alcohols. In all cases, only 1.5 equiv. of alcohol were used. The value of the method has been demonstrated by the racemization-free, catalytic alcoholysis of chiral amides yielded from other asymmetric methodologies.

Herein we report the synthesis of substituted indolizidines and related N-fused bicycles from simple saturated cyclic amines through sequential C-H and C-C bond functionalizations. Inspired by the Norrish-Yang Type II reaction, C-H functionalization of azacycles is achieved by forming alpha-hydroxy-beta-lactams from precursor alpha-ketoamide derivatives under mild, visible light conditions. Selective cleavage of the distal C(sp(2))-C(sp(3)) bond in alpha-hydroxy-beta-lactams using a Rh-complex leads to alpha-acyl intermediates which undergo sequential Rh-catalyzed decarbonylation, 1,4-addition to an electrophile, and aldol cyclization, to afford N-fused bicycles including indolizidines. Computational studies provide mechanistic insight into the observed positional selectivity of C-C cleavage, which depends strongly on the groups bound to Rh trans to the phosphine ligand.

I found the field of Chemistry very interesting. Saw the article alpha-Branched Ketone Dienolates: Base-Catalysed Generation and Regio- and Enantioselective Addition Reactions published in 2019.

In this study, the unique capacity of bifunctional BrOnsted bases to generate alpha-branched ketone dienolates and control both site- and stereoselectivity of their addition reactions to representative classes of carbon electrophiles (i.e., vinyl sulfones, nitroolefins, formaldehyde) is documented. We demonstrate that by using selected chiral tertiary amine/squaramide catalysts, the reactions of beta,gamma-unsaturated cycloalkanones proceed through the dienolate C alpha almost exclusively and provide all-carbon quaternary cyclic ketone adducts in good yields with very high enantioselectivities. A minor amount (<5%) of gamma-addition is observed when nitroolefins are used as electrophiles. The parent acyclic ketone dienolates proved to be less reactive under these conditions, and thus still constitute a challenging class of substrates. Quantum chemical calculations correctly predict these differences in reactivity and explain the observed site-specificity and enantioselectivity.

A simple and an efficient approach for in situ preparation of palladium nanoparticles (Pd NPs) in ionic liquid crystal (ILC) microemulsion is described. Microemulsion was formed by using a ternary mixture of triton X-100/ILC/water (in the ratio of 1.4:0.1:8.5). Three such microemulsions-1, 2 and 3 were formed by using three different ILCs namely ammonium ILC containing a cholesterol core (ILC-1), imidazolium ILC bearing a cholesterol core (ILC-2) and imidazolium ILC containing a biphenyl core (ILC-3), respectively. The Pd NPs were characterised using UV-vis spectroscopy, transmission electron microscopy and X-ray diffraction studies. Among the three, microemulsion-2 which was prepared using ILC-2 yielded stable NPs with an average particle size of similar to 20 nm. The NPs prepared in all three emulsions were examined as catalyst for Heck reaction. The catalytic efficiency was analysed for four cross-coupling reactions involving iodobenzene with different substituted alkenes namely methyl acrylate, ethyl acrylate, butyl acrylate and styrene. The coupling reactions were completed in a shorter period with good yields. Further, the recyclability test of Pd NPs revealed that the particles showed good activity until third catalytic cycle. The Pd NPs prepared in microemulsion-2 showed better activity compared to those prepared in microemulsions-1 and -3. (C) 2020 Elsevier B.V. All rights reserved.

The fabrication of durable and low-cost nanostructured materials remains important in chemical, biologic and medicinal applications. Particularly, iron-based nanomaterials are of central importance due to the ‘noble’ features of iron such as its high abundance, low cost and non-toxicity. Herein we report a simple sol-gel method for the synthesis of novel iron-titanium nanocomposite-based material (Fe9TiO15@TiO2). In order to prepare this material, we made a polymeric gel using ferrocene, titanium isopropoxide and THF precursors. The calcination of this gel in air at 500 degrees C produced Fe-Ti bimetallic nanoparticles-based composite and nano-TiO(2)as support. Noteworthy, our methodology provides an excellent control over composition, size and shape of the resulting nanoparticles. The resulted Fe-based material provides a sustainable catalyst for selective synthesis of anilines, which are key intermediates for the synthesis of several chemicals, dyes and materials, via reduction of structurally diverse and functionalized nitroarenes.

The aim of this research was to determine the chemical constituents and toxicity of the oil derived from Alpinia katsumadai seeds against Tribolium castaneum, Liposcelis bostrychophila and Lasioderma serricorne. The essential oil was obtained by hydrodistillation and was investigated by gas chromatograhy/mass spectrometry (GC/MS). The principal components of the essential oil were methyl cinnamate (64.2 %), cis-4-decen-1-ol (7.3 %) and octahydro-cis-2H-Inden-2-one (6.7 %). The essential oil and the two individial compounds exhibited potential insecticidal activities against three stored product insects. The essential oil possessed contact toxicity against T. castaneum, L. serricorne and L. bostrychophila (LD50 = 52.6 mu g/adult, 17.4 mu g/adult and 35.6 mu g/cm(2), respectively). Methyl cinnamate was the main contributor to its contact activity against T. castaneum, L. serricorne and L. bostrychophila (LD50 = 5.0 mu g/adult, 2.2 mu g/adult and 23.5 mu g/cm, respectively). The contact toxicity and repellent activity of the essential oil and cis-4-decen-1-ol against T. castaneum, L. bostrychophila and L. serricorne were recorded for the first time in this paper. A. katsumadai oil exhibited strong repellent activity against T. castaneum and L. bostrychophila, even at low concentrations. The results provide a basis of the development and utilization as biopesticide for control of insects.

A Cd(II)-based metal-organic framework as fluorescent chemical sensor, formulated as {[Cd-3(bmipia)(2)]center dot 10DMF center dot 5H(2)O}(n) (FCS-2), was synthesized through a hydrothermal process and structurally characterized via X-ray crystallography. FCS-2 represented a new three-dimensional framework assembled from a semi -rigid aromatic carboxylate ligand and exhibited fascinating fluorescence due to the highly crystalline and ordered molecular structure. The emission of FCS-2 could be quenched, interestingly, by the presence of trace 2,4,6-trinitrophenol, which indicated that FCS-2 can be applied as a potentially sensitive fluorescent chemical sensor for the detection of nitroaromatic compounds.
