39248-95-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 39248-95-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,2,4 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 39248-95:
(7*3)+(6*9)+(5*2)+(4*4)+(3*8)+(2*9)+(1*5)=148
148 % 10 = 8
So 39248-95-8 is a valid CAS Registry Number.

Method for synthesizing thioester through cross-coupling of visible light-catalyzed sodium sulfinate and acyl chloride

-

Paragraph 0040-0043, (2021/09/11)

The method takes sodium sulfinate and acyl chloride as raw materials and utilizes 2, 6 - dimethyl -1, 4 - dihydro -3, 5 - pyridine dicarboxylic acid diethyl ester and an organic alkali catalytic system to cross-couple sulfur radicals and acyl radicals und

Metal-free thioesterification of amides generating acyl thioesters

Wang, Qun,Liu, Long,Dong, Jianyu,Tian, Zhibin,Chen, Tieqiao

supporting information, p. 9384 - 9388 (2019/06/21)

A base-initiated thioesterification of amides with various thiols is reported. This reaction can take place efficiently under metal-free and air-atmospheric conditions, and provides a facile and practically useful approach to the synthesis of valuable acy

Oxalic Acid Monothioester for Palladium-Catalyzed Decarboxylative Thiocarbonylation and Hydrothiocarbonylation

Zhao, Bin,Fu, Yao,Shang, Rui

, p. 9521 - 9526 (2019/11/28)

Oxalic acid monothioester (OAM), an easily accessible and storable reagent, was reported herein as a thioester synthetic equivalent for palladium-catalyzed decarboxylative thiocarbonylation of organohalides and hydrothiocarbonylation of unsaturated carbon-carbon bonds at room temperature with high chemo- and regioselectivity. The reaction is applicable to the synthesis of cysteine-derived thioesters, thus allowing chemical modification of cysteine-containing peptides. Decarboxylation of OAM proceeds through oxidative addition of Pd(0) to the acyl-S bond, which accounts for the very mild reaction conditions.
