116690-69-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 116690-69-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,6,9 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 116690-69:
(8*1)+(7*1)+(6*6)+(5*6)+(4*9)+(3*0)+(2*6)+(1*9)=138
138 % 10 = 8
So 116690-69-8 is a valid CAS Registry Number.

Friedlaender synthesis of poly-substituted quinolines in the presence of triethylammonium hydrogen sulfate [Et3NH][HSO4] as a highly efficient, and cost effective acidic ionic liquid catalyst

Kermani, Esmat Tavakolinejad,Khabazzadeh, Hojatollah,Jazinizadeh, Tayebeh

, p. 1192 - 1196 (2011)

A rapid and an efficient method for the preparation of a variety of substituted quinolines has been developed through the reactions of o-aminoarylketones with carbonyl compounds containing a reactive α-methylene moiety in the presence of molten [Et3

Synthesis of quinolines via Friedlaender reaction catalyzed by CuBTC metal-organic-framework

Perez-Mayoral, Elena,Musilova, Zuzana,Gil, Barbara,Marszalek, Bartosz,Polozij, Miroslav,Nachtigall, Petr,Cejka, Jiri

, p. 4036 - 4044 (2012)

Friedlaender condensation between 2-aminoaryl ketones and different carbonyl compounds, catalyzed by CuBTC was investigated by a combination of various experimental techniques and by density functional theory based modelling. CuBTC exhibiting hard Lewis a

Rh-Catalyzed C-H Amination/Annulation of Acrylic Acids and Anthranils by Using -COOH as a Deciduous Directing Group: An Access to Diverse Quinolines

Gao, Yang,Nie, Jianhong,Li, Yibiao,Li, Xianwei,Chen, Qian,Huo, Yanping,Hu, Xiao-Qiang

supporting information, p. 2600 - 2605 (2020/04/02)

A method for the synthesis of diverse polysubstituted quinolines from readily available acrylic acids and anthranils has been developed. The weakly coordinating -COOH directing group, which can be tracelessly removed in the cascade cyclization, is essential for this reaction. Diverse polysubstituted quinolines were obtained under mild reaction conditions with simple H2O and CO2 as byproducts. More importantly, 1,2,3,4-tetrahydroacridine, which is the core skeleton of tacrine (an Alzheimer's disease drug), was conveniently synthesized.

ZnCl2 supported on Fe3O4@SiO2 core–shell nanocatalyst for the synthesis of quinolines via Friedl?nder synthesis under solvent-free condition

Soleimani, Ebrahim,Naderi Namivandi, Mahbobeh,Sepahvand, Heshmatollah

, (2017/02/05)

A magnetic nanocatalyst of Fe3O4@SiO2/ZnCl2 was prepared by supporting ZnCl2 on silica-coated magnetic nanoparticles of Fe3O4. This recoverable catalyst was used for the synthesi
