-
Paragraph 0027; 0041, (2021/04/14)
The invention discloses a method for synthesizing aryl benzyl ether compounds, which comprises the following steps: by using an iron (III) complex containing 1, 3-di-tert-butyl imidazole cations and having a molecular formula of [(tBuNCH = CHNtBu) CH] [FeBr4] as a catalyst and di-tert-butyl peroxide as an oxidant, carrying out oxidative coupling reaction on phenolic compounds and toluene compounds to synthesize the corresponding aryl benzyl ether compounds. The method is the first example for preparing the aryl benzyl ether compound through the oxidative coupling reaction of the phenolic compound and the toluene compound, which is realized by an iron-based catalyst, and has the advantages of atom economy, environmental friendliness and good substrate applicability.

Paragraph 0026-0027, (2021/04/26)
The invention discloses an application of an iron (III) complex containing 1,3-di-tert-butyl imidazole cations in synthesis of aryl benzyl ether compounds, and particularly relates to a method for synthesizing corresponding aryl benzyl ether compounds by taking di-tert-butyl peroxide as an oxidizing agent and carrying out oxidative coupling reaction on phenolic compounds and toluene compounds. According to the method, the iron (III) complex is used as the catalyst for the first time, and oxidative coupling of the phenolic compound and the toluene compound is realized. The method is the first oxidative coupling reaction of phenolic compounds and benzyl C(sp3)-H bonds, and a new method is provided for synthesizing aryl benzyl ether compounds. Compared with an existing synthesis method, the method provided by the invention avoids using toxic and polluting halogenated hydrocarbon and strong base, has better atom economy, and conforms to the development concept of green synthetic chemistry.

Rotondi, Giulia,Guglielmi, Paolo,Carradori, Simone,Secci, Daniela,De Monte, Celeste,De Filippis, Barbara,Maccallini, Cristina,Amoroso, Rosa,Cirilli, Roberto,Akdemir, Atilla,Angeli, Andrea,Supuran, Claudiu T.

A large library of derivatives based on the scaffold of 2-(benzylsulfinyl)benzoic acid were synthesised and tested as atypical inhibitors against four different isoforms of human carbonic anhydrase (hCA I, II, IX and XII, EC 4.2.1.1). The exploration of the chemical space around the main functional groups led to the discovery of selective hCA IX inhibitors in the micromolar/nanomolar range, thus establishing robust structure-activity relationships within this versatile scaffold. HPLC separation of some selected chiral compounds and biological evaluation of the corresponding enantiomers was performed along with molecular modelling studies on the most active derivatives.

Two new series of ring-opened analogues of cromakalim bearing sulfonylurea moieties (series A: with N-unmethylated sulfonylureas, series B: with N-methylated sulfonylureas) were synthesized and tested as relaxants of vascular and respiratory smooth muscle

Upon treatment with solely a hypervalent iodine reagent of phenyliodine(III) bis(trifluoroacetate) (PIFA), 3-(2-hydroxyphenyl)-3-oxo-N-phenyl propanamides and a series of its derivatives were conveniently converted to a class of undocumented spirofurooxindoles under mild conditions. Control experiments provided evidence that this spirocyclization process encompassed a cascade oxidative reactions involving the formation of a C?O bond prior to that of C?C bond. (Figure presented.).

C-H Functionalization via Remote Hydride Elimination: Palladium Catalyzed Dehydrogenation of ortho-Acyl Phenols to Flavonoids
Zhao, Xiaomei,Zhou, Jiabin,Lin, Shuying,Jin, Xukang,Liu, Renhua
supporting information, p. 976 - 979 (2017/03/14)
Although deprotonation of electron-poor C-H bonds to carbon anions with bases has long been known and widely used in organic synthesis, the hydride elimination from electron-rich C-H bonds to carbon cations or partial carbocations for the introduction of nucleophiles is a comparatively less explored area. Here we report that the carbonyl β-C(sp3)-H bond hydrogens of ortho-acyl phenols could be substituted by intramolecular phenolic hydroxyls to form O-heterocycles, followed by dehydrogenation of the O-heterocycle into flavonoids. The cascade reaction is catalyzed by Pd/C without added oxidants and sacrificing hydrogen acceptors.
Synthesis of Benzofurans from Ketones and 1,4-Benzoquinones
Wu, Fengtian,Bai, Rongxian,Gu, Yanlong
, p. 2307 - 2316 (2016/07/29)
Benzofuran derivatives can be synthesized through the sequential Michael addition and cyclization of 1,3-dicarbonyl compounds with 1,4-benzoquinones. However, ketones are rarely used in this reaction because of their low nucleophilicities. In this study, this problem was solved by utilizing triethyl orthoformate, which enabled the formation of a vinyl ethyl ether as an additive. As a result, the nucleophilicity of ketones increased. Many important 5-hydroxybenzofuran derivatives, which were not readily available by synthesis in the past, were also prepared via these newly established reactions. (Figure presented.) .
