It is known for its clear pale-yellow liquid form and its molecular formula is C11H14O3. 3-(2-HYDROXY-PHENYL)-PROPIONIC ACID ETHYL ESTER is used in various applications in the chemical industry, including being a significant intermediate in the production of other chemicals. Despite its wide usage, extensive care should be taken while handling this chemical as it may cause eye irritation, skin irritation, and other health hazards.

Check Digit Verification of cas no

The CAS Registry Mumber 20921-04-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,2 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20921-04:
(7*2)+(6*0)+(5*9)+(4*2)+(3*1)+(2*0)+(1*4)=74
74 % 10 = 4
So 20921-04-4 is a valid CAS Registry Number.

Ruthenium-catalyzed intramolecular arene C(sp2)-H amidation for synthesis of 3,4-dihydroquinolin-2(1 H)-ones

Au, Chi-Ming,Ling, Cho-Hon,Sun, Wenlong,Yu, Wing-Yiu

supporting information, p. 3310 - 3314 (2021/05/29)

We report the [Ru(p-cymene)(l-proline)Cl] ([Ru1])-catalyzed cyclization of 1,4,2-dioxazol-5-ones to form dihydroquinoline-2-ones in excellent yields with excellent regioselectivity via a formal intramolecular arene C(sp2)-H amidation. The reactions of the 2- and 4-substituted aryl dioxazolones proceeds initially through spirolactamization via electrophilic amidation at the arene site, which is para or ortho to the substituent. A Hammett correlation study showed that the spirolactamization is likely to occur by electrophilic nitrenoid attack at the arene, which is characterized by a negative ρ value of -0.73.

Catalytic activation of unstrained C(aryl)–C(aryl) bonds in 2,2′-biphenols

Zhu, Jun,Wang, Jianchun,Dong, Guangbin

, p. 45 - 51 (2018/11/23)

Transition metal catalysis has emerged as an important means for C–C activation that allows mild and selective transformations. However, the current scope of C–C bonds that can be activated is primarily restricted to either highly strained systems or more polarized C–C bonds. In contrast, the catalytic activation of non-polar and unstrained C–C moieties remains an unmet challenge. Here we report a general approach for the catalytic activation of the unstrained C(aryl)–C(aryl) bonds in 2,2′-biphenols. The key is to utilize the phenol moiety as a handle to install phosphinites as a recyclable directing group. Using hydrogen gas as the reductant, monophenols are obtained with a low catalyst loading and high functional group tolerance. This approach is also applied to the synthesis of 2,3,4-trisubstituted phenols. A further mechanistic study suggests that the C–C activation step is mediated by a rhodium(i) monohydride species. Finally, a preliminary study on breaking the inert biphenolic moieties in lignin models is illustrated.

Synthesis of the furo[2,3-b]chromene ring system of hyperaspindols a and B

Paterson, Danielle L.,Barker, David

supporting information, p. 265 - 270 (2015/04/14)

The synthesis of the unique furo[2,3-b]chromene ring system found in hyperaspidinols A and B, acylphloroglucinols from Hypericum chinense has been achieved in twelve steps. By comparison of the NMR spectra of the synthesized compounds with those of the natural products, a relative stereochemistry is suggested, especially that of the ketal carbon.
