Shen, Wen;Cunningham, Laura;Evans, Paul research published 《 Asymmetric synthesis of γ-amino-functionalized vinyl sulfones: De novo preparation of cysteine protease inhibitors》, the research content is summarized as follows. The enantioselective azo-based α-amination of an aldehyde followed by a Horner-Wadsworth-Emmons-based vinyl sulfone formation is reported. The thus obtained optically active N, N’-diprotected trans-(phenylsulfonyl)vinyl hydrazine products were then converted into the corresponding N-functionalized trans-(phenylsulfonyl)vinyl amines. Specifically, reaction of 4-phenylbutanal with di-tert-Bu azodicarboxylate (DBAD) in the presence of L– or D-proline, followed by addition of di-Et [(phenylsulfonyl)methyl]phosphonate, gave either enantiomer of di- tert-Bu trans-1-[5-phenyl-1-(phenylsulfonyl)pent-1-en-3-yl]hydrazine-1,2-dicarboxylate. The enantiomeric excesses of the (+)- and (-)-enantiomers prepared in this manner were in the range 86-89%. The conversion of these γ-hydrazino vinyl sulfones into the corresponding γ-amino-substituted compounds was achieved following a Boc (Boc = tert-butoxycarbonyl) deprotection, Zn reduction, N-functionalization sequence. This three-step sequence was reasonably efficient (approx. 50%) and no erosion of enantiopurity was found to have taken place.

Shahrokhinia, Ali;Rijal, Sahaj;Sonmez Baghirzade, Busra;Scanga, Randall A.;Biswas, Priyanka;Tafazoli, Shayesteh;Apul, Onur G.;Reuther, James F. research published 《 Chain Extensions in PhotoATRP-Induced Self-Assembly (PhotoATR-PISA): A Route to Ultrahigh Solids Concentrations and Click Nanoparticle Networks as Adsorbents for Water Treatment》, the research content is summarized as follows. Photocontrolled atom transfer radical polymerization induced self-assembly (PhotoATR-PISA) mediated by UV light (λ = 365 nm) was utilized to obtain polymer nanostructures with variable morphologies, including nanospheres, worm-like micelles and vesicles, at ambient temperature using ppm levels (ca. < 20 ppm) of copper catalyst. Using Cu(II)Br₂/tris(pyridin-2-ylmethyl)amine (TPMA) catalyst systems and functional ATRP initiators, PhotoATR-PISA was performed all in one-pot via sequential chain extension starting from solvophilic poly(oligo(ethylene glycol) Me ether methacrylate) (POEGMA) macroinitiator growth followed by PISA using different proportions of glycidyl methacrylate (GMA) and/or benzyl methacrylate (BMA) core-forming blocks forming alkyne-functional polymer nanoparticles. Remarkably, multiple, iterative chain extensions were accomplished introducing addnl. GMA and BMA monomers in multiple steps without addnl. solvent leading to stable nanoparticle dispersions with record-high final solid concentrations of 63 w% and 79 w%, resp. Core crosslinked nanoparticles (CCL NPs) were synthesized by incorporating N,N-cystamine bismethacrylamide (CBMA) crosslinkers in later stage chain extensions providing a route to CCL nanoworms. Furthermore, introducing BMA and GMA in varying orders sequentially allowed for the synthesis of sequence-controlled gradient copolymers, though this had limited effects on nanoparticle morphol. Finally, utilizing the copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) click reactions between alkyne-functionalized NPs and bisazide, telechelic poly(ethylene glycol) (PEG), nanostructured networks were fabricated consisting of nanospherical, beaded worm, nanoworm and vesicle morphologies.

Seo, Jia;Chen, Che-Wei;Lee, Woohyeong;Jeon, Ju Eun;Chen, Pei-Ling;Chuang, Shih-Ching;Joo, Jung Min research published 《 Palladium-Catalyzed C-H Benzannulation of Functionalized Furans and Pyrroles with Alkynes》, the research content is summarized as follows. A benzannulation strategy involving activation of two C-H bonds of five-membered heteroarenes was developed. Readily available furans and pyrroles stabilized by synthetically useful electron-withdrawing groups underwent Pd-catalyzed 1:2 annulation reactions with diaryl alkynes. A variety of functional groups, including ester, amide, ketone, aldehyde, and nitrile, on the heterocyclic cores were tolerated in the Pd-catalyzed oxidative reactions. In these reactions, the combination of 2,2-dimethylbutyric acid and its conjugate base facilitated metalation at the heteroaromatic rings and reoxidation of the Pd(0) species using oxygen as the terminal oxidant. This strategy provided fluorescent benzofuran and indole derivatives and was expected to allow for further development of functionalized polycyclic heteroaromatic compounds

Selli, Serkan;Guclu, Gamze;Sevindik, Onur;Yetisen, Mehmet;Kelebek, Hasim research published 《 Characterization of aroma-active compounds and stable carbon isotope ratios in Turkish pine honeys from two different regions》, the research content is summarized as follows. Turkey and Greece are the foremost countries in pine honey production, owing their reputation for this distinction to the natural distribution of pine (Pinus brutia and Pinus halepensis) trees found there. The aim of this study was to determine the effects of geog. differences on the aroma, aroma-active compounds, and other related properties of pine honey. Solvent-assisted flavor evaporation was applied to isolate aroma compounds in the pine honey samples. Aroma extract dilution anal. was used to screen the aroma-active compounds within the pine honey, using gas chromatog.-mass spectrometry-olfactometry. Pine honey from the Marmaris region of Turkey had a total volatile concentration of twofold of that found in Turkey’s Bolu region’s honey. Phenylacetaldehyde, exhibiting a honey and caramel odor note, was the most important aroma-active compound found in both pine honey samples. Along with aroma-active compounds, carbon isotope values, the textural, and color properties of the pine honeys were determined and compared in this study. Practical applications : Pine honey, especially in Turkey and Greece, has gained growing interest from both producers and consumers. Until recently, there has been a lack of information about its aroma-active compounds and some physicochem. characteristics. Therefore, this study focused on determining the aroma-active compounds, carbon isotope values, and textural properties of pine honey obtained from two different regions of Turkey. The results of this anal. showed that there are obvious differences in the types and content levels of volatile and aroma-active components found in the pine honey samples, depending on the region from which the honey was obtained. In addition, the carbon isotope ratio is a crucial parameter needed to identify and distinguish between the distinct honeys.
