14041-81-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 14041-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,0,4 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 14041-81:
(7*1)+(6*4)+(5*0)+(4*4)+(3*1)+(2*8)+(1*1)=67
67 % 10 = 7
So 14041-81-7 is a valid CAS Registry Number.

Hydrogen-bond-assisted transition-metal-free catalytic transformation of amides to esters

Huang, Changyu,Li, Jinpeng,Wang, Jiaquan,Zheng, Qingshu,Li, Zhenhua,Tu, Tao

, p. 66 - 71 (2020/11/18)

The amide C-N cleavage has drawn a broad interest in synthetic chemistry, biological process and pharmaceutical industry. Transition-metal, luxury ligand or excess base were always vital to the transformation. Here, we developed a transition-metal-free hydrogen-bond-assisted esterification of amides with only catalytic amount of base. The proposed crucial role of hydrogen bonding for assisting esterification was supported by control experiments, density functional theory (DFT) calculations and kinetic studies. Besides broad substrate scopes and excellent functional groups tolerance, this base-catalyzed protocol complements the conventional transition-metal-catalyzed esterification of amides and provides a new pathway to catalytic cleavage of amide C-N bonds for organic synthesis and pharmaceutical industry.

Photoinduced Specific Acylation of Phenolic Hydroxy Groups with Aldehydes

Ishida, Naoki,Kawasaki, Tairin,Murakami, Masahiro

supporting information, p. 18267 - 18271 (2020/08/21)

A convenient method is reported to specifically acylate phenolic hydroxyl groups through a radical pathway. When a mixture of an aldehyde and a phenol in ethyl acetate is irradiated with blue light in the presence of iridium and nickel bromide catalysts at ambient temperature, phenoxyl and acyl radicals are transiently generated in situ and cross-couple to furnish an ester. Aliphatic hydroxy groups remain untouched under the reaction conditions.
