5651-89-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5651-89-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,5 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5651-89:
(6*5)+(5*6)+(4*5)+(3*1)+(2*8)+(1*9)=108
108 % 10 = 8
So 5651-89-8 is a valid CAS Registry Number.

Paragraph 0051-0052, (2021/08/28)

The invention particularly relates to a method for preparing propyne aryl ether compounds from aryl phenol, halogenated propyne and derivatives of the halogenated propyne, and belongs to the technical field of preparation of the propyne aryl ether compoun

Enantioselective Palladium-Catalyzed Hydrophosphinylation of Allenes with Phosphine Oxides: Access to Chiral Allylic Phosphine Oxides

Wang, Jun,Yang, Zhiping

supporting information, p. 27288 - 27292 (2021/11/17)

A Pd-catalyzed hydrophosphinylation of alkyl and aryl-oxyallenes with phosphine oxides has been developed for the efficient and rapid construction of a family of chiral allylic phosphine oxides with a diverse range of functional groups. This methodology was further applied in the facile construction of chiral 2H-chromene and later stage functionalization of cholesterol.

Gold(III)-Catalyzed Intermolecular Oxidation-Cyclization of Ynones: Access to 4-Substituted Chroman-3-ones

Li, Jian,Yang, Fang,Ma, Yang-Ting,Ji, Kegong

supporting information, p. 2148 - 2153 (2019/03/28)

A synthesis of 4-substituted chroman-3-one derivatives has been developed through a gold(III) catalyzed oxidation-cyclization of ynones in good to excellent yield using easily prepared substrates. A broad range of synthetically useful functional groups (halide, alkene, alkyne, phenolic hydroxyl) were tolerated. Further application of this method paves a new way to prepare the skeleton of oblarotenoids. A cascade oxidative cyclization for construction of pyrano[2,3-c]chromen-1(5H)-one derivatives is also presented. (Figure presented.).

Electrostatic Control of Regioselectivity in Au(I)-Catalyzed Hydroarylation

, p. 444 - 457 (2017/04/13)

In the present paper 5-[4′-({4-[(4-aryloxy)methyl]-1H-1,2,3-triazol-1-yl}methyl)[1,1′-biphenyl]-2-yl]-1H-tetrazoles (5a–g) and [2′-(1H-tetrazol-5-yl)[1,1′-biphenyl]-4-yl]methyl-substituted-1-carbodithioates (11h–q) have been designed and synthesized. These compounds were subjected to docking (against AT1 receptor protein enzyme in complex with Lisinopril), in vitro angiotensin converting enzyme inhibition, anti-proliferative, anti-inflammatory screening (through egg albumin denaturation inhibition and red blood cell membrane stabilization assay) and finally anti-fungal activity analyses. Some of the compounds have shown significant pharmacological properties.

Synthesis of Tetrasubstituted α,β-Unsaturated Aldehydes via Radical 1,4-Aryl Migration/Trifluoromethylthiolation Cascade Reaction of Aryl Propynyl Ethers

Guo, Chun-Huan,Chen, Dao-Qian,Chen, Si,Liu, Xue-Yuan

supporting information, p. 2901 - 2906 (2017/09/08)

A one-pot synthesis of tetrasubstituted acrylaldehydes via difunctionalization of aryl propynyl ethers has been achieved, which involves a trifluoromethylthiolation process and a radical 1,4-aryl migration from oxygen to carbon. The reaction shows excellent conversion of aryl propynyl ethers into trifluoromethyl-containing α,β-unsaturated aldehydes through a radical pathway. (Figure presented.).
