The reaction of thiocarbonyl fluoride, generated from difluorocarbene, with various amines under mild conditions is described. Secondary amines, primary amines, and o-phenylenediamines are converted to thiocarbamoyl fluorides, isothiocyanates, and difluoromethylthiolated heterocycles, respectively. Thiocarbamoyl fluorides were further transformed into trifluoromethylated amines by using a one-pot process. Thiocarbonyl fluoride is generated in situ and is rapidly fully converted in one pot under mild conditions; therefore, no special safety precautions are needed.

An iconic textbook that pharmaceutical scientists encounter in undergraduate courses is ?Martin’s Physical Pharmacy and Pharmaceutical Sciences.? Within the chapter on Colloids, a figure indicates the location of solubilization of molecules within spherical, nonionic surfactant micelles. The surfactant consists of polyethylene glycol (PEG) hydrophilic headgroups and alkane chains for the hydrophobic tail. The figure shows benzene and toluene within the alkane core, salicylic acid (2-hydroxybenzoic acid) at the interface between the core and PEG chains, and then para-hydroxybenzoic acid (4-hydroxybenzoic acid) located between the PEG chains. Molecular dynamics simulations of octaethylene glycol monododecyl ether micelles were performed with a series of probe molecules, including those within the Martin’s figure, to determine their solubilization location. Relative placement of molecules within the micelle was correct; however, some specifics were different. In particular, benzene and toluene are excluded from the core, and 4-hydroxybenzoic acid prefers to maintain contact with the core. A series of molecules containing 6 carbon atoms were also studied to determine the effects of cyclization (moves out of core), polar functionalization (anchored to interface), and aromatization (excluded from central core). Molecular dynamics was found to be a useful tool for gaining insight into interactions important in solubilization of molecules.

New experimental data on heat capacities of pure liquid organic and some inorganic compounds were compiled, and recommended values were developed by critical assessment of literature calorimetrically determined heat capacities. The bulk of the work covered data published in the primary literature between 1993 and 1999 and some data of 2000. This paper presents a survey of some recent measurements of liquid heat capacity and highlights needs for new data on liquid heat capacity for large production organic contaminants, hazardous air pollutants and drinking water contaminants. Results of the critical assessment of data were published in the Journal of Physical and Chemical Reference Data.

A novel copper-catalyzed [3 + 2] cycloaddition reaction of alkynes with nitrile oxides generated in situ from the coupling reaction of copper carbene and nitroso radical has been developed. The three-component reaction provides a simple and efficient method for the construction of isoxazoles in a highly regioselective manner in a single step. On the basis of the experimental results and density functional theory calculations, a catalytic cycle (CuI-CuII-Cu0-CuI) for this cascade cyclization reaction is proposed.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C9H11NO3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 21080-81-9, in my other articles.

Unlimited growth of cancer cells requires an extensive nutrient supply. To meet this demand, cancer cells drastically upregulate glucose uptake and metabolism compared to normal cells. This difference has made the blocking of glycolysis a fascinating strategy to treat this malignant disease. alpha-enolase is not only one of the most upregulated glycolytic enzymes in cancer cells, but also associates with many cellular processes or conditions important to cancer cell survival, such as cell migration, invasion, and hypoxia. Targeting alpha-enolase could simultaneously disturb cancer cells in multiple ways and, therefore, is a good target for anticancer drug development. In the current study, more than 22 million chemical structures meeting the criteria of Lipinski?s rule of five from the ZINC database were docked to alpha-enolase by virtual screening. Twenty-four chemical structures with docking scores better than that of the enolase substrate, 2-phosphoglycerate, were further screened by the absorption, distribution, metabolism, excretion, and toxicity (ADMET) properties prediction. Four of them were classified as non-mutagenic, non-carcinogenic, and capable of oral administration where they showed steady interactions to alpha-enolase that were comparable, even superior, to the currently available inhibitors in molecular dynamics (MD) simulation. These compounds may be considered promising leads for further development of the alpha-enolase inhibitors and could help fight cancer metabolically.

A variety of 1-aryl-1,2,3-triazoles containing heteroarenes at C2-, C3- or C4-positions on the aryl ring was successfully prepared via palladium-catalysed direct arylation. These couplings were performed employing 1 mol% of phosphine-free Pd(OAc)2catalyst with 1-(bromophenyl)-1,2,3-triazoles and heteroarenes as coupling partners. A wide variety of heteroarenes such as thiazoles, thiophenes, furans, pyrroles or isoxazoles was tolerated.

C?N bond formation is regarded as a very useful and fundamental reaction for the synthesis of nitrogen-containing molecules in both organic and pharmaceutical chemistry. Noble-metal and homogeneous catalysts have frequently been used for C?N bond formation, however, these catalysts have a number of disadvantages, such as high cost, toxicity, and low atom economy. In this work, a low-toxic and cheap iron complex (iron ethylene-1,2-diamine) has been loaded onto carbon nanotubes (CNTs) to prepare a heterogeneous single-atom catalyst (SAC) named Fe-Nx/CNTs. We employed this SAC in the synthesis of C?N bonds for the first time. It was found that Fe-Nx/CNTs is an efficient catalyst for the synthesis of C?N bonds starting from aromatic amines and ketones. Its catalytic performance was excellent, giving yields of up to 96 %, six-fold higher than the yields obtained with noble-metal catalysts, such as AuCl3/CNTs and RhCl3/CNTs. The catalyst showed efficacy in the reactions of thirteen aromatic amine substrates, without the need for additives, and seventeen enaminones were obtained. High-angle annular dark-field scanning transmission electron microscopy in combination with X-ray absorption spectroscopy revealed that the iron species were well dispersed in the Fe-Nx/CNTs catalyst as single atoms and that Fe-Nx might be the catalytic active species. This Fe-Nx/CNTs catalyst has potential industrial applications as it could be cycled seven times without any significant loss of activity.

The biological activity of Mannich bases, a structurally heterogeneous class of chemical compounds that are generated from various substrates through the introduction of an aminomethyl function by means of the Mannich reaction, is surveyed, with emphasis on the relationship between structure and biological activity. The review covers extensively the literature reports that have disclosed Mannich bases as anticancer and cytotoxic agents, or compounds with potential antibacterial and antifungal activity in the last decade. The most relevant studies on the activity of Mannich bases as antimycobacterial agents, antimalarials, or antiviral candidates have been included as well. The review contains also a thorough coverage of anticonvulsant, anti-inflammatory, analgesic and antioxidant activities of Mannich bases. In addition, several minor biological activities of Mannich bases, such as their ability to regulate blood pressure or inhibit platelet aggregation, their antiparasitic and anti-ulcer effects, as well as their use as agents for the treatment of mental disorders have been presented. The review gives in the end a brief overview of the potential of Mannich bases as inhibitors of various enzymes or ligands for several receptors.
