Total Synthesis and Anti-Cancer Activity of All Known Communesin Alkaloids and Related Derivatives was written by Pompeo, Matthew M.;Cheah, Jaime H.;Movassaghi, Mohammad. And the article was included in Journal of the American Chemical Society in 2019.Electric Literature of C12H20O6 This article mentions the following:

A unified enantioselective total synthesis and anticancer evaluation of all known epoxide-containing communesin alkaloids and related derivatives is described. Our synthesis is predicated on the convergent and modular diazene-directed assembly of two complex fragments to secure the critical C3a-C3a’ linkage followed by a guided biomimetic aminal reorganization to deliver the heptacyclic core of these alkaloids. Concise enantioselective syntheses of the fragments were devised, with highlights including the application of a rationally designed sulfinamide chiral auxiliary, an efficient calcium trifluoromethanesulfonate promoted intramol. amination, and a diastereoselective epoxidation that simultaneously converts the new chiral auxiliary to a versatile amine protective group. The modularity of our convergent approach enabled the rapid synthesis of all epoxide-containing members of the communesin family from a single heterodimeric intermediate, including the first total synthesis of communesins C-E, and G-I, and facilitated our stereochem. revision of (-)-communesin I, the most recently isolated communesin alkaloid. Furthermore, the generality of our biogenetically inspired heterodimer rearrangement was demonstrated in a guided synthesis of a communesin derivative with an unnatural topol. Finally, we report the first comparative anal. of the anticancer activities of all naturally occurring communesin alkaloids A-I and eight complex derivatives against five human cancer cell lines. From these data, we have identified (-)-communesin B as the most potent natural communesin and discovered that derivatives with N8′-sulfonamide substitution exhibit up to a 10-fold increase in potency over the natural alkaloids. Safety advised in use of toxic trimethylsilyl cyanide. In the experiment, the researchers used many compounds, for example, (3aR,5S,6S,6aR)-5-((R)-2,2-Dimethyl-1,3-dioxolan-4-yl)-2,2-dimethyltetrahydrofuro[2,3-d][1,3]dioxol-6-ol (cas: 582-52-5Electric Literature of C12H20O6).

THF (Tetrahydrofuran) is a stable compound with relatively low boiling point and excellent solvency. THF can also be synthesized by catalytic hydrogenation of furan. This allows certain sugars to be converted to THF via acid-catalyzed digestion to furfural and decarbonylation to furan, although this method is not widely practiced. THF is thus derivable from renewable resources.Electric Literature of C12H20O6

A novel and efficient method for the synthesis of difluoroalkylated benzofuran, benzothiophene, and indole derivatives via palladium-catalyzed aryldifluoroalkylation of 1,6-enynes with Et difluoroiodoacetate and arylboronic acids has been established. High reaction efficiency, mild conditions, broad substrate scope, and good functional group tolerance are the features of this protocol. Notably, the resultant products can be smoothly converted into CF₂-containing benzofurans, benzothiophenes and indoles through an isomerization process catalyzed by Fe(OTf)₃.

Elucidating coding of taste qualities with the taste modifier miraculin in the common marmoset was written by Danilova, Vicktoria;Hellekant, Goeran. And the article was included in Brain Research Bulletin in 2006.COA of Formula: C28H38O19 This article mentions the following:

To investigate the relationships between the activity in different types of taste fibers and the gustatory behavior in marmosets, we used the taste modifier miraculin, which in humans adds a sweet taste quality to sour stimuli. In behavioral experiments, we measured marmosets’ consumption of acids before and after tongue application of miraculin. In electrophysiol. experiments responses of single taste fibers in chorda tympani and glossopharyngeal nerves were recorded before and after tongue application of miraculin. We found that after miraculin marmosets consumed acids more readily. Taste nerve recordings showed that after miraculin taste fibers which usually respond only to sweeteners, S fibers, became responsive to acids. These results further support our hypothesis that the activity in S fibers is translated into a hedonically pos. behavioral response. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7COA of Formula: C28H38O19).

Conformational Lock of Glycosyl Donors Using Cyclic Carbamates was written by Villameriel, Jaime Moyano;Pedersen, Christian Marcus. And the article was included in European Journal of Organic Chemistry in 2020.Computed Properties of C12H20O6 This article mentions the following:

Axial rich glycosyl donors often display superior reactivity and stereoselectivity in glycosylation. In this study, a glucosamine glycosyl donor, locked in a ¹C₄ conformation by a six-membered carbamate ring, i.e. an oxazinone, is synthesized and studied. The 2N,4O carbamate is synthesized in one step from the corresponding azide. The glycosylation properties were studied by glycosylation of different alcs. Derivatives of the glycosyl donor were synthesized by introducing Ac, Troc, Ts, and Ms groups on the oxazinone nitrogen. The ring opening to give the glycoside in the ⁴C₁ conformation was found to proceed smoothly using Zemplen conditions. In the experiment, the researchers used many compounds, for example, (3aR,5S,6S,6aR)-5-((R)-2,2-Dimethyl-1,3-dioxolan-4-yl)-2,2-dimethyltetrahydrofuro[2,3-d][1,3]dioxol-6-ol (cas: 582-52-5Computed Properties of C12H20O6).

Opposite fates of the purine metabolite allantoin under water and nitrogen limitations in bread wheat was written by Casartelli, Alberto;Melino, Vanessa J.;Baumann, Ute;Riboni, Matteo;Suchecki, Radoslaw;Jayasinghe, Nirupama S.;Mendis, Himasha;Watanabe, Mutsumi;Erban, Alexander;Zuther, Ellen;Hoefgen, Rainer;Roessner, Ute;Okamoto, Mamoru;Heuer, Sigrid. And the article was included in Plant Molecular Biology in 2019.Formula: C18H32O16 This article mentions the following:

Abstract: The metabolite allantoin is an intermediate of the catabolism of purines (components of nucleotides) and is known for its housekeeping role in nitrogen (N) recycling and also for its function in N transport and storage in nodulated legumes. Allantoin was also shown to differentially accumulate upon abiotic stress in a range of plant species but little is known about its role in cereals. To address this, purine catabolic pathway genes were identified in hexaploid bread wheat and their chromosomal location was exptl. validated. A comparative study of two Australian bread wheat genotypes revealed a highly significant increase of allantoin (up to 29-fold) under drought. In contrast, allantoin significantly decreased (up to 22-fold) in response to N deficiency. The observed changes were accompanied by transcriptional adjustment of key purine catabolic genes, suggesting that the recycling of purine-derived N is tightly regulated under stress. We propose opposite fates of allantoin in plants under stress: the accumulation of allantoin under drought circumvents its degradation to ammonium (NH₄⁺) thereby preventing N losses. On the other hand, under N deficiency, increasing the NH₄⁺ liberated via allantoin catabolism contributes towards the maintenance of N homeostasis. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9Formula: C18H32O16).

Solid acid catalysis, and the advantages often associated with their use, have been proved equally efficient for the synthesis of tetrahydrofurans or furans. Tetrahydrofuran can also be produced, or synthesised, via catalytic hydrogenation of furan. This process involves converting certain sugars into THF by digesting to furfural. An alternative to this method is the catalytic hydrogenation of furan with a nickel catalyst.Formula: C18H32O16

Stereoselective Synthesis of 1,1′-Disaccharides by Organoboron Catalysis was written by Izumi, Sanae;Kobayashi, Yusuke;Takemoto, Yoshiji. And the article was included in Angewandte Chemie, International Edition in 2020.Electric Literature of C12H20O6 This article mentions the following:

The highly stereoselective synthesis of 1,1′-disaccharides was achieved by using 1,2-dihydroxyglycosyl acceptors and glycosyl donors in the presence of a tricyclic borinic acid catalyst. In this reaction, the complexation of the diols and the catalyst is crucial for the activation of glycosyl donors, as well as for the 1,2-cis-configuration of the products. The anomeric stereochem. of the glycosyl donor depends on the employed glycosyl donor. Applications of the produced 1,1′-disaccharides are also described. In the experiment, the researchers used many compounds, for example, (3aR,5S,6S,6aR)-5-((R)-2,2-Dimethyl-1,3-dioxolan-4-yl)-2,2-dimethyltetrahydrofuro[2,3-d][1,3]dioxol-6-ol (cas: 582-52-5Electric Literature of C12H20O6).

Effect of amorphization method on the physicochemical properties of amorphous sucrose was written by Morrow, Elizabeth A.;Terban, Maxwell W.;Thomas, Leonard C.;Gray, Danielle L.;Bowman, Michael J.;Billinge, Simon J. L.;Schmidt, Shelly J.. And the article was included in Journal of Food Engineering in 2019.Recommanded Product: (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol This article mentions the following:

Our objective was to characterize the physicochem. properties of amorphous sucrose prepared by freeze-drying (FreD), spray-drying (SprayD), ball milling (BallM), melt-quenching (MeltQ), and spin-melt-quenching (SpinMeltQ). SEM indicated that FreD, SprayD, BallM, and SpinMeltQ formed distinct particles, while MeltQ formed a single mass. Powder X-ray diffraction confirmed that BallM was semi-crystalline, while FreD, SprayD, MeltQ, and SpinMeltQ were amorphous. However, total scattering pair distribution function anal. of synchrotron X-ray diffraction data suggested that local mol.-level ordering differences existed between MeltQ and FreD, SprayD, and SpinMeltQ. Chromatog. analyses revealed that thermal decomposition indicator compounds were present in BallM, MeltQ, and SpinMeltQ, but not in FreD and SprayD. All samples exhibited a glass transition. Addnl., FreD, SprayD, BallM, and SpinMeltQ exhibited an exothermic cold crystallization peak, but MeltQ did not. Overall, this research provides evidence that sucrose is a material whose physicochem. properties are strongly influenced by amorphization method.
