21943-45-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21943-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,4 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21943-45:
(7*2)+(6*1)+(5*9)+(4*4)+(3*3)+(2*4)+(1*5)=103
103 % 10 = 3
So 21943-45-3 is a valid CAS Registry Number.

Alkylation of quinoxalin-2(1H)-ones using phosphonium ylides as alkylating reagents

Liu, Jun-Jia,Peng, Sha,Yang, Luo

supporting information, p. 9705 - 9710 (2021/11/30)

A practical and efficient methodology for the construction of 3-alkylquinoxalinones through base promoted direct alkylation of quinoxalin-2(1H)-ones with phosphonium ylides as alkylating reagents under metal- and oxidant-free conditions was developed. Various 3-alkylquinoxalin-2(1H)-ones were easily obtained in good to excellent yields. Tentative mechanistic studies suggest that this reaction is likely to involve a nucleophilic addition-elimination process.

Preparation method of 3-methylquinoxaline-2(1H)-one compounds

-

Paragraph 0084-0086, (2019/08/12)

The invention discloses a preparation method of 3-methylquinoxaline-2(1H)-one compounds. The preparation method comprises the step of performing a visible light catalytic reaction on a quinoxaline ketone compound and iodobenzene diacetate under the action

Visible-light induced decarboxylative alkylation of quinoxalin-2(1H)-ones at the C3-position

Xue, Wenxuan,Su, Yingpeng,Wang, Ke-Hu,Zhang, Rong,Feng, Yawei,Cao, Lindan,Huang, Dangfeng,Hu, Yulai

, p. 6654 - 6661 (2019/07/16)

A simple and efficient method for the visible light induced direct carbon alkylation of quinoxalin-2(1H)-ones at the C3 position is described. This protocol employs cheap and readily available phenyliodine(iii) dicarboxylates as the alkylation reagents to conduct decarboxylative radical coupling reaction with quinoxalin-2(1H)-ones. The process exhibits excellent compatibility to functional groups and provides a convenient and selective access to various 3-alkylquinoxalin-2(1H)-ones in good yields.

Metal-free regioselective formation of C-N and C-O bonds with the utilization of diaryliodonium salts in water: Facile synthesis of: N-Arylquinolones and aryloxyquinolines

Mehra, Manish Kumar,Tantak, Mukund P.,Arun,Kumar, Indresh,Kumar, Dalip

supporting information, p. 4956 - 4961 (2017/07/10)

Regioselective construction of crucial C-N and C-O bonds leading to N-Arylquinolones and aryloxyquinolines has been accomplished by employing easily accessible diaryliodonium salts and quinolones in water under metal-and ligand-free conditions. This opera
