493021-43-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 493021-43-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,3,0,2 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 493021-43:
(8*4)+(7*9)+(6*3)+(5*0)+(4*2)+(3*1)+(2*4)+(1*3)=135
135 % 10 = 5
So 493021-43-5 is a valid CAS Registry Number.

DMSO as a Methine Source in TFA-Mediated One-Pot Tandem Regioselective Synthesis of 3-Substituted-1-Aryl-1 H-Pyrazolo-[3,4- b]quinolines from Anilines and Pyrazolones

Yadav, Pushpendra,Awasthi, Annapurna,Gokulnath, Sabapathi,Tiwari, Dharmendra Kumar

, p. 2658 - 2666 (2021/02/01)

An acid-mediated and DMSO participant one-pot tandem synthesis of 3-substituted-1-aryl-1H-pyrazolo-[3,4- b]quinoline from readily available anilines and pyrazolones was achieved. This method enables regioselective construction of the valuable heterocycles under transition-metal and oxidant-free conditions in which DMSO acts as a methine source as well as solvent making this process an environmentally benign approach. A broad range of diversely substituted aryl amines and pyrazolines are successfully employed in this reaction to access a series of pyrazolo[4,3-c]quinolones through a novel cascade mechanism. Furthermore, the application and mechanistic studies of the present methodology also demonstrated.

It was proposed a method of synthesis several 6-styrylo1-1H-pyrazolo[3,4-b]quinolines as promising material for optoelectronics. Particularly, 6-styryl-1,3-diphenyl-1H-pyrazolo[3,4-b]quinolines were prepared by Wadsworth-Emmons reaction. One of advantageo

1,3-Diphenyl-1H-pyrazolo[3,4-b]quinoline: A Versatile Fluorophore for the Design of Brightly Emissive Molecular Sensors

Rurack, Knut,Danel, Andrzej,Rotkiewicz, Krystyna,Grabka, Danuta,Spieles, Monika,Rettig, Wolfgang

, p. 4647 - 4650 (2007/10/03)

(Matrix Presented) The 1.3-diphenyl-1H-pyrazolo[3,4-b]-quinoline chromophore is a versatile building block for the construction of brightly fluorescent molecular sensors. Facile synthetic procedures allow integration of the chromophore into fluorophore-spacer-receptor systems as well as fluoroionophores operating via intramolecular charge transfer. Whereas the former photoinduced electron-transfer probes show strong analyte-induced fluorescence enhancement, the latter exhibit bright ratiometric dual emission. Employing prototype macrocyclic receptors, the favorable signaling features for metal ion recognition are demonstrated.
