Simple and efficient catalytic routes have been explored to upgrade the raw lignin oil. Though homogeneous catalysis is easy to operate and possesses a high reaction rate, it also suffers from the difficulty of product separation In this work, we used H₃BO₃ as a novel homogeneous catalyst coupled with Ru/C to overcome the separation problem and carry out the hydrodeoxygenation (HDO) of phenolic compounds and raw lignin oil. H₃BO₃ showed an outstanding performance over the liquid organic and mineral acids, with a good catalyst recyclability. Phenolic model compounds including monomers and dimers can be efficiently converted into cycloalkanes with yields close to 100%. Moreover, the raw lignin oil also had a good HDO result by using this bifunctional catalyst (H₃BO₃ and Ru/C). The content of hydrocarbons increased from 7.9% to 93.1% at 260°C, which promoted the upgraded lignin oil capable to be used as fuel directly. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Application of 103-16-2).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Application of 103-16-2

Discovery of 5-bromo-4-phenoxy-N-phenylpyrimidin-2-amine derivatives as novel ULK1 inhibitors that block autophagy and induce apoptosis in non-small cell lung cancer was written by Sun, Dejuan;Yang, Zijian;Zhen, Yongqi;Yang, Yushang;Chen, Yanmei;Yuan, Yong;Zhang, Lan;Zeng, Xiaoxi;Chen, Lixia. And the article was included in European Journal of Medicinal Chemistry in 2020.Recommanded Product: 4-Benzyloxyphenol The following contents are mentioned in the article:

5-Bromo-4-phenoxy-N-phenylpyrimidin-2-amine derivatives were synthesized and evaluated as ULK1 inhibitors in non-small cell lung cancer. Among all the obtained ULK1 inhibitors, 5-bromo-4-(2-fluoro-4-nitrophenoxy)-N-(3,4,5-trimethoxyphenyl) pyrimidin-2-amine, was the most active one. The docking anal. was conducted to compare 5-bromo-4-(2-fluoro-4-nitrophenoxy)-N-(3,4,5-trimethoxyphenyl) pyrimidin-2-amine and SBI-0206965, which further elucidated the roles of the H-bond donor. This compound inhibited the proliferation of A549 cells and showed strong inhibitory activity against ULK1 kinase. Moreover, we found that 5-bromo-4-(2-fluoro-4-nitrophenoxy)-N-(3,4,5-trimethoxyphenyl) pyrimidin-2-amine could induce apoptosis while simultaneously blocking autophagy. Collectively, these findings shed new light on 5-bromo-4-(2-fluoro-4-nitrophenoxy)-N-(3,4,5-trimethoxyphenyl) pyrimidin-2-amine that would be utilized as a promising candidate drug for the future NSCLC therapy. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Recommanded Product: 4-Benzyloxyphenol).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Recommanded Product: 4-Benzyloxyphenol

Functionalized Triphenylene Discotic Molecules: Synthesis and Mesomorphic Characterizations was written by Srinivasa, H. T.;Hariprasad, S.. And the article was included in ChemistrySelect in 2022.HPLC of Formula: 103-16-2 The following contents are mentioned in the article:

The synthesis and characterization of two sets of triphenylene derived discotic mols. with phenol, aldehyde and acid functional groups was reported. In the first set, triphenylene moiety was tethered with benzene derivatives via an ester linkage, while in the second set via an ether linkage with increased aromatic conjugation. All the mols. have triphenylene disk at one end and with benzene, biphenyl and terphenyl cores at the other end connected via flexible methylene spacers. The chem. structures of the novel compounds were confirmed by IR, NMR spectroscopy and CHN anal. methods. Thermal and liquid crystal texture properties were determined using differential scanning calorimetry, polarized optical microscope and X-ray diffraction studies. Amongst all the novel compounds, only the terphenyl derivative displayed mesomorphism. However, their charge transfer complexes with trinitrofluorenone (TNF) an electron acceptor exhibited columnar mesophases. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2HPLC of Formula: 103-16-2).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Oxoammonium salts are catalysing efficient and selective halogenation of olefins, alkynes and aromatics was written by Wang, Weijin;Li, Xinyao;Yang, Xiaoxue;Ai, Lingsheng;Gong, Zhiwen;Jiao, Ning;Song, Song. And the article was included in Nature Communications in 2021.Category: ethers-buliding-blocks The following contents are mentioned in the article:

Herein, TEMPO (2,2,6,6-tetramethylpiperidine nitroxide) and its derivatives are disclosed as active catalysts for electrophilic halogenation of olefins e.., prop-1-en-1-ylbenzene, alkynes R¹CCR² (R¹ = octyl, Ph; R² = H, Me, n-Bu, Ph), and aromatics R³H (R³ = 3-(carboxymethyl)-4-methoxybenzen-1-yl, 2-[ethoxy(oxo)methane]-1H-indol-3-yl, 5-phenylthiophen-2-yl, etc.). These catalysts are stable, readily available, and reactive enough to activate haleniums including Br⁺, I⁺ and even Cl⁺ reagents. This catalytic system is applicable to various halogenations including haloarylation of olefins or dibromination of alkynes, which were rarely realized in previous Lewis base catalysis or Lewis acid catalysis. The high catalytic ability is attributed to a synergistic activation model of electrophilic halogenating reagents, where the carbonyl group and the halogen atom are both activated by present TEMPO catalysis.

Acetyl-CoA carboxylase (ACC) is a crucial enzyme in fatty acid metabolism, which plays a major role in the occurrence and development of certain tumors. Herein, one potential ACC inhibitor () was identified through high-throughput virtual screening (HTVS), and a series of 4-phenoxy-Ph isoxazoles were synthesized for structure-activity relationship (SAR) studies. Among these compounds, exhibited the most potent ACC inhibitory activity (IC50=99.8 nM), which was comparable to that of CP-640186. Moreover, the antiproliferation assay revealed that compound exhibited the strongest cytotoxicity, with IC50 values of 0.22μM (A549), 0.26μM (HepG2), and 0.21μM (MDA-MB-231), resp. The preliminary mechanistic studies on and suggested that the compounds decreased the malonyl-CoA levels, arrested the cell cycle at the G0/G1 phase, and induced apoptosis in MDA-MB-231 cells. Overall, these results indicated that the 4-phenoxy-Ph isoxazoles are potential for further study in cancer therapeutics as ACC inhibitors.
