Carbon-11 (β⁺ emitter, t_1/2 = 20.4 min) radiolabeled L-glutamine is a potentially useful mol. imaging agent that can be utilized with positron emission tomog. for both human oncol. diagnosis and plant imaging research. Based upon a previously reported [¹¹C]cyanide end-capping labeling method, a systematic investigation of nucleophilic cyanation reactions and acidic hydrolysis reaction parameters, including base, metal ion source, phase transfer catalyst, solvent, reaction temperature and reaction time, was conducted. The result was a milder, more reliable, two-step method which provides L-[5-¹¹C]-glutamine with a radiochem. yield of 63.8 ± 8.7% (range from 51 to 74%, n = 10) with >90% radiochem. purity and >90% enantiomeric purity. The total synthesis time was 40-50 min from the end of bombardment. In addition, an Fmoc derivatization method was developed to measure the specific activity of this radiotracer.

Mannancherry, Rajesh published the artcileMolecular dynamic staircases: all-carbon axial chiral “Geländer” structures, Name: Dimethyl 2-iodoterephthalate, the publication is Chemical Science (2018), 9(26), 5758-5766, database is CAplus and MEDLINE.

Herein, the syntheses of two tightly packed all-carbon “Geländer” mols. with axial chirality are described. Motivated by our previous results, we further reduced the bridge length by excluding the heteroatoms. The absolute configuration was determined by comparison of the measured and calculated CD (CD) spectra and the thermodn. stability was determined by dynamic high-performance liquid chromatog. (HPLC) and CD anal. The cyclophanes were fully characterized by CD measurements, X-ray diffraction (XRD) anal., NMR, UV-Vis and high resolution mass spectrometry (HRMS). Our novel all-carbon macrocycle is the most stable Geländer system reported so far.

The cyclodehydration of (2-carboxyphenylamino)benzoic acids I (R = NO₂, CO₂H, Cl, Br, etc.) by H₂SO₄, POCl₃, or by Et polyphosphate to give mixtures of dihydroacridinecarboxylic acids II and III depended on the electronic and steric effects of R. Judicious choice of substituent and cyclizing reagent gave a large excess of 1 isomer.

Bousrez, Guillaume published the artcileReady Access to Anhydrous Anionic Lanthanide Acetates by Using Imidazolium Acetate Ionic Liquids as the Reaction Medium, COA of Formula: C6H13I, the publication is Chemistry – A European Journal (2021), 27(52), 13181-13189, database is CAplus and MEDLINE.

Access to lanthanide acetate coordination compounds is challenged by the tendency of lanthanides to coordinate water and the plethora of acetate coordination modes. A straightforward, reproducible synthetic procedure by treating lanthanide chloride hydrates with defined ratios of the ionic liquid (IL) 1-ethyl-3-methylimidazolium acetate ([C₂mim][OAc]) has been developed. This reaction pathway leads to two isostructural crystalline anhydrous coordination complexes, the polymeric [C₂mim]_n[{Ln₂(OAc)₇}_n] and the dimeric [C₂mim]₂[Ln₂(OAc)₈], based on the ion size and the ratio of IL used. A reaction with an IL : Ln-salt ratio of 5 : 1, where Ln = Nd, Sm, and Gd, led exclusively to the polymer, while for the heaviest lanthanides (Dy-Lu) the dimer was observed Reaction with Eu and Tb resulted in a mixture of both polymeric and dimeric forms. When the amount of IL and/or the size of the cation was increased, the reaction led to only the dimeric compound for all the lanthanide series. Crystallog. analyses of the resulting salts revealed three different types of metal-acetate coordination modes where η²μκ² is the most represented in both structure types.

Puguan, John Marc C. published the artcileAchieving transmissive-to-black chromism via engineered dual electro-thermoresponsive single-molecule for full modulation of solar transmittance, Related Products of iodides-buliding-blocks, the publication is Chemical Engineering Journal (Amsterdam, Netherlands) (2022), 437(Part_1), 135157, database is CAplus.

Pursuit of complete and null transmissive optical material in smart windows for full control of the intensity and spectrum of incoming solar light has led to the advancement of transmissive-to-black chromism. While most reported transmissive-to-black devices are elec. stimulated, we report here an alternative approach based on dual stimulation of a new dual responsive mol. By integrating asym. viologen onto a newly engineered poly(2-isopropyl-2-oxazoline)-based mol., one can achieve transmissive-to-black chromism. The synergistic effect of its thermochromic and electrochromic response when stimulated simultaneously shows full absorption of the entire visible solar spectrum resulting to a truly black state that is ideal for building facades requiring absolute privacy. Autonomous chromic switchability function is also possible by independently stimulating the material either elec. or thermally where it displays unique colored state of vibrant magenta and a hazy state, resp. Tunability of the material’s overall performance in terms of optical contrast, switching kinetics, coloration efficiency and cyclic stability based on the lattice water concentration was elucidated in this work. Furthermore, the fabricated device displays self-bleaching property and has a short-term “memory” effect that may broaden its potential for other applications.
