The CAS is 90-16-4. Through research, I have a further understanding and discovery of Benzo[d][1,2,3]triazin-4(3H)-one

Metal-free, visible-light-induced denitrogenative phosphorylation of 1,2,3-benzotriazinones was achieved. With the use of eosin Y as a photoredox catalyst, N,N-diisopropylethylamine as a base, CH3CN-H2O as a solvent and sunlight or a blue LED as a light source, a variety of aryl-phosphonates, aryl-phosphinates, and aryl-phosphine oxides were efficiently prepared. In addition, B(2)pin(2) instead of P-nucleophiles as a radical acceptor was also demonstrated. The key advantages of this newly developed method are the clean reaction profile, use of a low-cost organic-dye catalyst, energy efficiency, broad substrate scope, good to excellent yields and large-scale synthetic applicability. The gram-scale synthesised compounds could be isolated in pure form just upon extraction, followed by re-crystallisation; no tedious chromatographic purification was required.

The Name is Diphenylmethanamine. Through research, I have a further understanding and discovery of 91-00-9.

The development of efficient and eco-friendly methods for the synthesis of elaborate amines is highly desired as they are valuable chemicals. The catalytic alkylation of amines using alcohols as alkylating agents, through the so-called borrowing hydrogen process, satisfies several of the principles of green chemistry. In this paper, four neutral half-sandwich complexes of Ru(II), Rh(III), and Ir(III) have been synthesized and tested as catalysts in theN-benzylation of amines with benzyl alcohol. The new derivatives contain aN(boolean AND)N ‘ anionic ligand derived from 5-(pyridin-2-ylmethylene)hydantoin (Hpyhy) that has never been tested in metal complexes with catalytic applications. In particular, the Ir derivatives, [(Cp*)IrX(pyhy)] (X = Cl or H), exhibit high activity along with good selectivity in the process. Indeed, the scope of the optimized protocol has been proved in the benzylation of several primary and secondary amines. The selectivity towards monoalkylated or dialkylated amines has been tuned by adjusting the amine:alcohol ratio and the reaction time. Experimental results support a mechanism consisting of three consecutive steps, two of which are Ir catalyzed, and a favorable condensation step without the assistance of the catalyst. Moreover, an unproductive competitive pathway can operate when the reaction is performed in open-air vessels, due to the irreversible release of H-2. This route is hampered when the reaction is carried out in close vessels, likely because the release of H(2)is reversed through metal-based heterolytic cleavage. From our viewpoint, these results show the potential of the new catalysts in a very attractive and promising methodology for the synthesis of amines.

The CAS is 104-10-9. Through research, I have a further understanding and discovery of 2-(4-Aminophenyl)ethanol.

A new metal-free procedure allowing Csp(3)-N bond formation through coupling of pyridotriazoles and weakly nucleophilic anilines has been developed. This sustainable reaction shows high tolerance towards functional groups (ketones, free alcohols) leading to 2-picolylamine derivatives. The key to our success is the use of a catalytic amount of TBAB and water as a co-solvent leading to the formation of pyridylalkylamine derivatives. As this coupling tolerates the presence of Csp(2)-Br bond on both partners of the reaction, we performed a sequential one-pot reaction between functionalized triazolopyridines and anilines followed by a second coupling with N-tosylhydrazones leading to the formation of Csp(3)-N and Csp(2)-Csp(2) bonds.

Construction of N-substituted pyrrolidones from biomass-derived levulinic acid (LA) via reductive amination is a highly attractive route for biomass valorization. However, realizing this transformation using H-2 as the hydrogen source under mild conditions is still very challenging. Herein, we designed porous TiO2 nanosheets-supported Pt nanoparticles (Pt/P-TiO2) as the heterogeneous catalyst. The prepared Pt/P-TiO2 was highly efficient for reductive amination of LA to produce various N-substituted pyrrolidones (34 examples) at ambient temperature and H-2 pressure. Meanwhile, Pt/P-TiO2 showed good applicability for reductive amination of levulinic esters, 4-acetylbutyric acid, 2-acetylbenzoic acid, and 2-carboxybenzaldehyde. Systematic studies indicated that the strong acidity of P-TiO2 and the lower electron density of the Pt sites as well as the porous structure resulted in the excellent activity of Pt/P-TiO2.

The NLRP3 inflammasome is a component of the innate immune system involved in the production of proinflammatory cytokines. Aberrant activation by a wide range of exogenous and endogenous signals can lead to chronic, low-grade inflammation. It has attracted a great deal of interest as a drug target due to the association with diseases of large unmet medical need such as Alzheimer’s disease, Parkinson’s disease, arthritis, and cancer. To date, no drugs specifically targeting inhibition of the NLRP3 inflammasome have been approved. In this work, we used the known NLRP3 inflammasome inhibitor CP-456,773 (aka CRID3 or MCC 950) as our starting point and undertook a Structure-Activity Relationship (SAR) analysis and subsequent scaffold-hopping exercise. This resulted in the rational design of a series of novel ester-substituted urea compounds that are highly potent and selective NLRP3 inflammasome inhibitors, as exemplified by compounds 44 and 45. It is hypothesized that the ester moiety acts as a highly permeable delivery vehicle and is subsequently hydrolyzed to the carboxylic acid active species by carboxylesterase enzymes. These molecules are greatly differentiated from the state-of-the-art and offer potential in the treatment of NLRP3-driven diseases, particularly where tissue penetration is required.

In one-pot strategy, diazotization of methyl anthranilate 5 followed by addition of amino acid ester hydrochloride, we have prepared methyl-2-(4-oxobenzotriazin-3(4H)-yl)-alkanoates 6a-c. Starting with hydrazides 7a,b, N-alkyl-2-(4-oxobenzotriazin-3(4H)-yl)-alkanamides 9-10(a-h) and methyl-2-(2-(4-oxobenzotriazin-3(4H)-yl)alkanamido)alkanoates 11- 12(a-e) were prepared via azide coupling. Hydrazones 13-15 were prepared via condensation of hydrazides 7a,b with 4-methoxybenzaldehyde, 4-dimethylaminobenzaldehyde, and/or arabinose. Molecular docking was done for synthesized compounds using MOE 2008-10 software. The compounds 9a, 12a, 12c, 13a, 13b, and 14b have the most pronounced strong binding affinities toward the target E. coli Fab-H receptor, whereas compounds 3, 11e, 12e, and 13a have the most pronounced strong binding affinities toward the target vitamin D receptor. The in vitro antibacterial activities of the highest binding affinity docked compounds were tested against E. coli, Staphylococcus aureus, and Salmonella spp. Majority of the tested compounds showed effective positive results against E. coli, while they were almost inactive against Staphylococcus aureus and Salmonella spp. The in vitro cytotoxic activities of the highest binding affinity-docked compounds were tested against the human liver carcinoma cell line (HepG2). Some compounds showed potent cytotoxic activity with low IC50 values, especially for 3 (6.525 mu M) and 13a (10.97 mu M) than that for standard drug doxorubicin (2.06 mu M).
