Lu, Qixing; Wang, Tao; Wu, Qian; Cheng, Lijing; Luo, Han; Liu, Lei; Chu, Guobiao; Wang, Lufeng; Li, Baosheng published an article in 2022, the title of the article was C-H heteroarylation of aromatics via catalyst free SN2′ coupling cycloaromatization.Quality Control of 2-Methoxynaphthalene And the article contains the following content:

The construction of a carbon-carbon bond is the most fundamental aspect of synthetic chem. In this study, authors developed a catalyst-free SN2′ reaction of β-OTf-substituted enamides with aromatics to obtain aryl-substituted aza-1,4-dicarbonyl compounds that can be in situ transformed into aryl-imidazole, aryl-thiazole, and aryl-oxazole in one-pot operation, thus achieving C-H heteroarylation of aromatics This simple, efficient, clean and scalable strategy, which provides difficult-to-realize biaryl products, is compatible with various aromatics having varying complexities. This method can be used for the late-stage modification of various com. pharmaceuticals or functional materials and offers an orthogonal approach for constructing biaryl compounds The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Quality Control of 2-Methoxynaphthalene

On December 21, 2001, Wu, Zhong-Liu; Li, Zu-Yi published an article.COA of Formula: C10H12O3 The title of the article was Enantioselective hydrolysis of various racemic α-substituted arylacetonitriles using Rhodococcus sp. CGMCC 0497. And the article contained the following:

The enantioselective hydrolysis of 17 racemic α-substituted arylacetonitriles by Rhodococcus sp. CGMCC 0497 is described. The corresponding (R)-amides and (S)-acids were obtained with excellent enantiomeric excess in most cases. The effect of steric and electronic factors on the outcome of the reactions are discussed here. The results prove that nitrile-converting enzymes are efficient tools for the synthesis of sterically unencumbered chiral α-arylpropionic acids and amides. The experimental process involved the reaction of (S)-2-(2-Methoxyphenyl)propanoic acid(cas: 81616-80-0).COA of Formula: C10H12O3

And the article contained the following:

Owing to both Lewis and Bronsted acid active sites on sulfated polyborate under homogeneous conditions, iodination protocol of arenes was developed, which can meet the requirement of regioselectivity and higher yield. The sulfated polyborate activated N-iodosuccinimide for mono iodination of highly activated substrates viz. phenols, anilines under anhydrous condition. Water tuned sulfated polyborate to generate more Bronsted acid sites resulting in rapid activation of NIS for diiodination. The protocol was equally applicable to diiodination of 4-hydroxyphenylacetic acid to synthesize 4-hydroxy-3,5-diiodophenylacetic acid, an intermediate of tiratricol, a thyroid treatment drug. This protocol was further integrated via one-pot sequential iodination and Sonogashira coupling to synthesize aryl acetylenes, building blocks for the synthesis of a variety of specialty chems., API and natural products.

Shigeno, Masanori; Hayashi, Kazutoshi; Korenaga, Toshinobu; Nozawa-Kumada, Kanako; Kondo, Yoshinori published an article in 2022, the title of the article was Organic superbase t-Bu-P4-catalyzed demethylations of methoxyarenes.Related Products of 93-04-9 And the article contains the following content:

The organic superbase t-Bu-P4 catalyzes the demethylation reactions of methoxyarenes ROMe [R = 4-cyanophenyl, 1-oxo-2,3-dihydro-1H-inden-5-yl, 1-benzothiophen-5-yl, etc.] in the presence of alkanethiol and hexamethyldisilazane was reported. The system can efficiently convert a variety of substrates, including electron-deficient, -neutral, and -rich substrates and heteroaromatic substrates, and displays excellent functional group tolerance. Computational studies show that the high reactivity achieved by t-Bu-P4 is due to the formation of the nucleophilic naked thiolate species.
