Check Digit Verification of cas no

The CAS Registry Mumber 21923-41-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,2 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21923-41:
(7*2)+(6*1)+(5*9)+(4*2)+(3*3)+(2*4)+(1*1)=91
91 % 10 = 1
So 21923-41-1 is a valid CAS Registry Number.

Preparation of 2-arninpbenzophenones and polysubstituted quinolines through Sml2 promoted reductive cleavage of 3-aryl-2,1-benzisoxazoles

Fan, Xuesen,Zhang, Xinying,Zhang, Yongmin

, p. 637 - 643 (2005)

Promoted by SmI2, 3-aryl-2,1-benzisoxazoles underwent reductive cleavage of the N - O bond leading to 2-aminobenzophenones in high yields upon protonation. Otherwise, if ketones with active methylene group were added to the reaction mixture prior to protonation, the desired poly substituted quinolines could be obtained under mild conditions in a one-pot manner.

An efficient method for carbon-carbon bond formation is described. The process employs the palladium-catalyzed and copper-mediated cross-coupling of quinoline-2-(1 H)-thiones with arylboronic acids or alkynes through C-S bond cleavage without an inert atm

Cobalt-Catalyzed Electrophilic Aminations with Anthranils: An Expedient Route to Condensed Quinolines

Li, Jie,Tan, Eric,Keller, Niklas,Chen, Yi-Hung,Zehetmaier, Peter M.,Jakowetz, Andreas C.,Bein, Thomas,Knochel, Paul

supporting information, p. 98 - 103 (2019/01/08)

The reaction of various organozinc pivalates with anthranils provides anilines derivatives, which cyclize under acidic conditions providing condensed quinolines. Using alkenylzinc pivalates, electron-rich arylzinc pivalates or heterocyclic zinc pivalates produces directly the condensed quinolines of which several structures belong to new heterocyclic scaffolds. These N-heterocycles are of particular interest for organic light emitting diodes with their high photoluminescence quantum yields and long exciton lifetimes as well as for hole-transporting materials in methylammonium lead iodide perovskites solar cells due to an optimal band alignment for holes and a large bandgap.

Electrophilic Cyclization of 2-Aminophenylprop-1-yn-3-ols into 3-Iodo-6-(aryldiazenyl)quinolines by Using a One-Pot Azo-Coupling and Iodocyclization Sequence

Catalyst free indirect Friedlaender synthesis of substituted quinolines from alcohols in PEG-400

The synthesis of substituted quinolines can be easily and greenly accomplished by the direct reaction between the corresponding aminoalcohol and ketone using PEG-400 as reaction medium in the presence of a base, without any transition-metal catalyst.

InCl3-driven regioselective synthesis of functionalized/ annulated quinolines: Scope and limitations

Chanda, Tanmoy,Verma, Rajiv Kumar,Singh, Maya Shankar

supporting information; experimental part, p. 778 - 787 (2012/06/29)

The efficient, regioselective synthesis of functionalized/annulated quinolines was achieved by the coupling of 2-aminoaryl ketones with alkynes/active methylenes/α-oxoketene dithioacetals promoted by InCl 3 in refluxing acetonitrile as well as under solvent-free conditions in excellent yields. This transformation presumably proceeded through the hydroamination-hydroarylation of alkynes, and the Friedlaender annulation of active methylene compounds and α-oxoketene dithioacetals with 2-aminoarylketones. In addition, simple reductive and oxidative cyclization of 2-nitrobenzaldehyde and 2-aminobenzylalcohol, respectively, afforded substituted quinolines. Systematic optimization of the reaction parameters allowed us to identify two-component coupling (2CC) conditions that were tolerant of a wide range of functional groups, thereby providing densely functionalized/annulated quinolines. This approach tolerates the synthesis of various bioactive quinoline frameworks from the same 2-aminoarylketones under mild conditions, thus making this strategy highly useful in diversity-oriented synthesis (DOS). The scope and limitations of the alkyne-, activated methylene-, and α-oxoketene dithioacetal components on the reaction were also investigated.
