A new class of calamitic 1,3,4-oxadiazole monomers H-shaped dimers , and calix [4]arene-based tetramer have been synthesized and characterized fully by means of ¹H NMR (proton NMR), ¹³C-NMR, high resolution mass spectroscopy (HRMS) and elemental anal., and the thermal properties and photoluminescent behaviors have been investigated systemically. All of the monomers display stable liquid crystalline properties with smectic and/or nematic mesophases determined by the electronic and steric nature of the terminal groups. In contrast, both the H-shaped dimers and the calix [4]arene based tetramer are not mesogenic, while they show specific recognition for Cu²⁺ through the fluorescent emission intensity quenching. The relationship between the mol. structures and properties has been discussed according to the mol. shapes.

Wu, Fu-Peng published the artcileCopper-Catalyzed Borylative Methylation of Alkyl Iodides with CO as the C1 Source: Advantaged by Faster Reaction of CuH over CuBpin, Application In Synthesis of 638-45-9, the publication is Angewandte Chemie, International Edition (2021), 60(21), 11730-11734, database is CAplus and MEDLINE.

CuH and CuBpin are versatile catalysts and intermediates in organic chem. However, studies that involve both CuH and CuBpin in the same reaction is still rarely reported due to their high reactivity. Now, a study on CuH- and CuBpin-catalyzed borylative methylation of alkyl iodides with CO as the C1 source is reported. Various one carbon prolongated alkyl boranes (RCH₂Bpin and RCH(Bpin)₂) were produced in moderate to good yields from the corresponding alkyl iodides (RI). In this cooperative system, CuH reacts with alkyl iodide faster than CuBpin.

A copper-catalyzed alkoxycarbonylation transformation of unactivated alkyl iodides was developed. Various alkyl iodides were converted into the corresponding tert-Bu esters in good yields. NaOt-Bu acts as both a nucleophile and a base. Moreover, other types of aliphatic esters was also be obtained in moderated yields if extra alcs. are added.

Yu, Tao published the artcileDiscovery of dimethyl pent-4-ynoic acid derivatives, as potent and orally bioavailable DGAT1 inhibitors that suppress body weight in diet-induced mouse obesity model, Category: iodides-buliding-blocks, the publication is Bioorganic & Medicinal Chemistry Letters (2018), 28(10), 1686-1692, database is CAplus and MEDLINE.

Diacylglycerol acetyltransferase (DGAT) is expressed abundantly in intestine, liver, and adipose tissues. DGAT1 is the crucial and rate-limiting enzyme that mediates the final step in triacylglycerol (TAG) resynthesis during dietary fat absorption. However, too much triacylglycerol (TAG) reserve will lead to genetic obesity (Hubert et al., 2000). DGAT1 knockout mice could survive and displayed a reduction in the postprandial rise of plasma TG, and increased sensitivity of insulin and leptin. Here the authors report the discovery and characterization of a novel selective DGAT1 inhibitor 29 (5-(4-(4-amino-5-oxo-7,8-dihydropyrimido[5,4f][1,4] oxazepin-6(5H)-yl)-2,6-dimethylphenyl)-3,3-dimethylpent-4-ynoic acid) to potentially treat obesity. Compound 29 showed lipid lowering effect in mouse lipid tolerance test (LTT) and also reduced body weight in DIO mice without observable liver damage.

Guo, Yongxian published the artcileForce-Induced Molecular Isomerization for the Construction of Multicolor Luminescent Segmented Molecular Crystals, Related Products of iodides-buliding-blocks, the publication is Advanced Optical Materials (2022), 10(2), 2101794, database is CAplus.

Multicolor luminescent segmented materials have attracted tremendous research interest due to their potential applications as barcoding materials in information security and anti-counterfeiting. Although much effort has been devoted to the preparation of photonic barcodes based on different light-emitting materials, the rational design of barcoding materials with well-controlled emission color and length at desired position remains a challenge. Here, a novel strategy to fabricate multicolor luminescent segmented 1D mol. crystals is reported by manipulating the mol. conformation and intermol. interactions of the mechanochromic crystals, which are assembled from a rationally designed twisting conjugated mol. The emission color of these mechanochromic crystals changes from green to orange with the mechanism of synergy effect of force-induced mol. isomerization from trans to cis state and mol. packing changes from cross to parallel, which is revealed by single crystal X-ray diffraction. Multicolor luminescent segmented 1D microribbons are fabricated by applying precisely controlled forces by tapping mode at. force microscope, which shows the encoding capability. These findings provide a new method that allows the controllable fabrication of segmented materials with tunable emission color and length at desired position toward barcoding applications.

Siebum, Arjan H. G. published the artcileAccess to any site-directed isotopomer of methionine, selenomethionine, cysteine, and selenocysteine – use of simple, efficient modular synthetic reaction schemes for isotope incorporation, Quality Control of 161370-66-7, the publication is European Journal of Organic Chemistry (2004), 2905-2913, database is CAplus.

Simple modular reaction schemes that allow access to any isotopomer of protected serine and homoserine have been worked out. These systems could be simply converted into cysteine, selenocysteine, homocysteine, homoselenocysteine, the essential amino acid methionine, and selenomethionine by Mitsunobu chem. These sulfur- and selenium-containing amino acids fulfil many essential roles in the living organism. In addition, homoserine could be converted in a few steps into optically active L-vinylglycine. As well as the stable isotopes ¹³C, ¹⁵N, ¹⁷O, and ¹⁸O, the radioactive isotopes of sulfur, selenium and carbon can also be easily introduced in a site-directed fashion. In view of the wide scope of the Mitsunobu reaction, we feel that many more important systems with the carbon skeleton of serine and homoserine should be preparable through this basic chem. in any site-directed isotopically labeled form.

R¹CH:CRCOCH₂COCO₂Et (I, R = H, Me, Ph; R¹ = 3-methylbenzofuran-2-yl, 2-phenyl-2H-1,2,3-triazol-4-yl) were prepared by condensing R¹CH:CRCOMe (II) with Et oxalate in dry ether. Treating I with hydrazine and arylhydrazines caused cyclization to the corresponding Et substituted pyrazole-3-carboxylates, e.g., III, which were hydrolyzed to acids or converted into acid hydrazides. Condensing I with acylhydrazines gave hydrazones which were cyclized to the corresponding N-acylpyrazoles. Treating I with HONH₂ gave 3,5-disubstituted isoxazoles, e.g., IV, whereas using o-phenylenediamine gave hydroxyquinoxalines. Reaction of II with arylhydrazines gave the corresponding hydrazones, which on boiling with EtOH-HCl cyclized to pyrazolines. Treating the latter compounds with excess bromine-water gave the brominated pyrazoles. Condensing II with acylhydrazines gave the corresponding acylhydrazones.

The marked changes which are brought about in the 1000-cm.^-1 region of the infrared spectrum of pyridine on the addition of I are generally characteristic of amine-halogen solutions Infrared studies on a series of solutions of amines and halogens revealed corresponding infrared shifts. Several new solid amine-halogen complexes were isolated, and, in every case, the frequency shifts in solution were correlated with infrared bands characteristic of the solids.
