70959-90-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70959-90-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,9,5 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 70959-90:
(7*7)+(6*0)+(5*9)+(4*5)+(3*9)+(2*9)+(1*0)=159
159 % 10 = 9
So 70959-90-9 is a valid CAS Registry Number.

Synthesis of benzo[f]indole-4,9-dione and benzo[b]carbazole-6,11-dione derivatives via one-pot sequential C,N-dialkylation of enaminones of β-diketones and ketoesters by 2,3-dichloronaphthoquinone

Hu, Hua-You,Liu, Yun,Ye, Miao,Xu, Jian-Hua

, p. 1913 - 1917 (2006)

Direct one-pot syntheses of benzo[f]indole-4,9-dione and benzo[b]carbazole-6,11-dione derivatives have been achieved in moderate to high yields via sequential C,N-dialkylation of the monoenamines of β-dicarbonyl compounds (the β-enaminones) by 2,3-dichlor

Cerium salts in the oxidative free radical reactions between 2-amino-1,4-naphthoquinones and β-dicarbonyl compounds

Tseng, Chih-Chung,Wu, Yi-Lung,Chuang, Che-Ping

, p. 7625 - 7633 (2002)

The oxidative free radical reactions between 2-amino-1,4-naphthoquinones and β-dicarbonyl compounds mediated by cerium(IV) salts are described. In contrast to those mediated by manganese(III) acetate, the cerium(IV) mediated free radical reaction provides a novel method for the synthesis of benzo[f]indole-4,9-diones exclusively. This high selectivity is due to the strong oxaphilicity of the cerium salts.

Solvent effects on the oxidative free radical reactions of 2-amino-1,4-naphthoquinones

Tseng, Chao-Ming,Wu, Yi-Lung,Chuang, Che-Ping

, p. 12249 - 12260 (2004)

Solvent effects on the manganese (III) initiated oxidative free radical reactions of 2-amino-1,4-naphthoquinones are described. This free radical reaction provides a novel method for the synthesis of benzo[f]indole-4,9-diones, benzo[f]indole-2,4,9-triones, benzo[b]carbazole-6,11-diones and benzo[b]acridine-6,11-diones. High chemoselectivity was observed in different solvents. Graphical Abstract

Gold-catalyzed cascade C-C and C-N bond formation: Synthesis of polysubstituted indolequinones and pyrroles

Abdukader, Ablimit,Xue, Qicai,Lin, Aijun,Zhang, Ming,Cheng, Yixiang,Zhu, Chengjian

supporting information, p. 5898 - 5900 (2013/10/21)

The combination of Ph3PAuCl and AgOTf was proven to be an efficient catalyst for the cascade C-C and C-N bond formation reactions from enamines and bromoquinones or nitroolefins. This protocol affords a straightforward method for the synthesis of polysubstituted indolequinones and pyrroles in good yields.
