Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of Heterocyclic Chemistry called ZnO nanorods as efficient catalyst for the green synthesis of thiophene derivatives: Investigation of antioxidant and antimicrobial activity, Author is Hamedani, Naghmeh Faal; Ghazvini, Maryam; Sheikholeslami-Farahani, Fatemeh; Bagherian-Jamnani, Mohammad Taghi, which mentions a compound: 70-23-5, SMILESS is O=C(OCC)C(CBr)=O, Molecular C5H7BrO3, Recommanded Product: Ethyl 3-bromo-2-oxopropanoate.

In this work, thiophene derivatives I [R = 4-H3CC6H4, 4-H3COC6H4, 4-O2NC6H4, CH3CH2OC(O); R1 = Me, Et; R2 = 4-H3CC6H4, 4-H3COC6H4] were synthesized in good yields via multicomponent reaction of isoquinoline, alkyl bromides BrCH2C(O)R, activated acetylenic compounds R1OC(O)CCC(O)OR1, isothiocyanates R2N=C=S, and catalytic amounts of ZnO nanorods (NRs) at room temperature under solvent-free conditions.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone, is researched, Molecular C12H16N2O2, CAS is 67914-60-7, about Tetra-(acetyl piperazine phenoxy) phthalocyaninato zinc complexes and their proteins conjugates: synthesis, characterisation and photodynamic activities, the main research direction is tetra acetyl piperazine phenoxy phthalocyaninato zinc protein conjugate photodynamic.Category: oxazolidine.

Two zinc phthalocyanines, tetra-α-[4-(4-acetyl piperazine) phenoxy] phthalocyaninato zinc (C80H72N16O8Zn) and tetra-β-[4-(4-acetyl piperazine) phenoxy] phthalocyaninato zinc (C80H72N16O8Zn), have been synthesized and characterized with 1H NMR, MS, IR and elemental anal. The electronic absorption spectra of two complexes in common organic solvents (N,N-DMF, THF, n-octanol) were typical for nonaggregated phthalocyanines, showing a Q band at 693∼698 nm for 1 and 681 ∼ 682 nm for 2. This indicates that the Q band of zinc phthalocyanine with the substituted groups located in the α position is largely red shifted than that in the β position. The spectral features of complexes 1 and 2 in aqueous media suggest the α-substituted groups are more effective than β-substituted groups to hinder the aggregation of phthalocyanine mol. The interactions between two complexes with serum albumin and transferrin (BSA, HSA and apoTf) were investigated by absorption and fluorescence spectroscopy. The binding constants were found to be (1 ∼ 20) × 105 mol-1·L. By comparison, β-substituted 2 had stronger combining ability with albumin than that of α-substituted 1. The non-covalent conjugates (1-BSA, 2-BSA, 1-HSA, 1-apoTf and 1-FeTf) with the molar ratio of about 1 : 1 have also been prepared The photodynamic activities of two complexes and their bioconjugates against MCF-7 mammary tumor cells were examined The result shows that the photocytotoxicities of conjugates are higher than that of complexes 1 ∼ 2 and follows the order 1-BSA > 1-FeTf > 1-HSA, 1-apoTf > 2-BSA > 1>2.

Author is Beyzavi, Hudson; Mandal, Debashis; Strebl, Martin G.; Neumann, Constanze N.; D’Amato, Erica M.; Chen, Junting; Hooker, Jacob M.; Ritter, Tobias.

The deficiency of robust and practical methods for 18F-radiofluorination is a bottleneck for positron emission tomog. (PET) tracer development. Here, we report the first transition-metal-assisted 18F-deoxyfluorination of phenols. The transformation benefits from readily available phenols as starting materials, tolerance of moisture and ambient atm., large substrate scope, and translatability to generate doses appropriate for PET imaging.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Gas-Phase Formation and Isomerization Reactions of Cyanoacetaldehyde, a Prebiotic Molecule of Astrochemical Interest, published in 2021-05-20, which mentions a compound: 288-42-6, mainly applied to gas phase formation isomerization reaction prebiotic mol cyanoacetaldehyde, Quality Control of Oxazole.

Cyanoacetaldehyde (NC-CH2CH=O) is considered, together with guanidine and urea, as a precursor of the pyrimidine bases cytosine and uracil. Although it has not yet been detected in the interstellar medium (ISM), several hypotheses have been put forward about its synthesis in solution and in the gas phase. In this paper, we present a gas-phase model of the barrierless reaction between formyl (HCO) and cyanomethyl (CH2CN) radicals leading to cyanoacetaldehyde and focus on its evolution through isomerization and dissociation pathways. The potential-energy surface for all reactions has been explored by DFT calculations employing double-hybrid functionals and further refined through the “”Cheap”” composite scheme. Our results indicate that the direct association of the two reacting radicals (HCO and CH2CN) is strongly exothermic and thus thermodynamically favored under the harsh conditions of the ISM. Microcanonical rate constants computed with the help of the StarRate program for energies up to 6 kJ mol-1 above the dissociation limit show that the most abundant products are the two conformers of cyanoacetaldehyde (nitrile and carbonyl groups in a cis or trans configuration) which, despite having comparable stability, are obtained with a cis/trans ratio of 0.35:0.65. The formation of other products with relative abundances not exceeding 10% is also discussed.

Star-shaped polymers have unique phys. properties and they are sought after materials in industry. However, the ease of synthesis is essential for translation of these materials into large-scale applications. Herein, a highly efficient synthetic method to prepare star-shaped polymers by combination of Cu-mediated reversible deactivation radical polymerization (Cu-RDRP) and thiol-bromo click reaction is described. Well-defined linear and block polymers with a very high bromine chain end fidelity are obtained via Cu-RDRP and subsequently react with multi-functional thiol compounds High coupling efficiencies of larger than 90% are obtained owing to the quick and efficient reaction between thiols and alkyl bromides. Moreover, the arms of the obtained star-shaped polymers are linked via thioether bonds to the core, making them susceptible for oxidative degradation
