5,7-bis(1,1-dimethylethyl)-3-(4-methoxyphenyl)-(3H)-benzofuran-2-one is a complex organic compound with a molecular formula of C21H24O4. It is characterized by a benzofuran-2-one core structure, which features a benzene ring fused to a furan ring, with a carbonyl group at the 2-position. The compound has two tert-butyl groups (1,1-dimethylethyl) at the 5 and 7 positions, which contribute to its steric hindrance and stability. Additionally, it has a 4-methoxyphenyl group attached at the 3-position, providing an electron-donating methoxy group that can influence the compound's reactivity and physical properties. This chemical is known for its potential applications in the synthesis of pharmaceuticals and other specialty chemicals, where its unique structure may confer specific biological activities or reactivity profiles.

75869-37-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75869-37-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,8,6 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75869-37:
(7*7)+(6*5)+(5*8)+(4*6)+(3*9)+(2*3)+(1*7)=183
183 % 10 = 3
So 75869-37-3 is a valid CAS Registry Number.

Sequential Continuous-Flow Synthesis of 3-Aryl Benzofuranones

Xin, Hai-Long,Rao, Xiaofeng,Ishitani, Haruro,Kobayashi, Shū

, p. 1906 - 1910 (2021/06/27)

A sequential continuous-flow system to produce 3-aryl benzofuranones was developed. Starting from 2,4-di-tert-butylphenol and glyoxylic acid monohydrate, both the initial cyclocondensation and the subsequent Friedel?Crafts alkylation were catalyzed by the same heterogeneous catalyst, Amberlyst-15H. The catalyst has a promising life-time for these two steps, and it was able to be recovered and reused for several runs without deactivation. By using the established flow system, 5,7-di-tert-butyl-3-(3,4-dimethylphenyl)-3H-benzofuran-2-one (Irganox HP-136), which is a commercial antioxidant, was prepared in 88% two-step yield. Reactions with various aromatic compounds proceeded well under flow conditions to afford 3-aryl benzo-furanone derivatives in high yields with good functional group compatibility.

A versatile new synthesis of 3-aryl-3H-benzofuran-2-ones

Nesvadba, Peter,Bugnon, Lucienne,Dubs, Paul,Evans, Samuel

, p. 863 - 864 (2007/10/03)

Aromatic or heteroaromatic hydrocarbons are easily alkylated with 3- hydroxy-3H-benzofuran-2-ones under Friedel-Crafts or acid catalysis to afford 3-aryl-3H-benzofuran-2-ones in good yield. Access to the starting 3-hydroxy- 3H-benzofuran-2-ones is easily achievable by reaction of suitably substituted phenols with glyoxylic acid.
