189634-91-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 189634-91-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,6,3 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 189634-91:
(8*1)+(7*8)+(6*9)+(5*6)+(4*3)+(3*4)+(2*9)+(1*1)=191
191 % 10 = 1
So 189634-91-1 is a valid CAS Registry Number.

Metal-Free C?H Borylation of N-Heteroarenes by Boron Trifluoride

Iashin, Vladimir,Berta, Dénes,Chernichenko, Konstantin,Nieger, Martin,Moslova, Karina,Pápai, Imre,Repo, Timo

supporting information, p. 13873 - 13879 (2020/10/02)

Organoboron compounds are essential reagents in modern C?C coupling reactions. Their synthesis via catalytic C?H borylation by main group elements is emerging as a powerful tool alternative to transition metal based catalysis. Herein, a straightforward metal-free synthesis of aryldifluoroboranes from BF3 and heteroarenes is reported. The reaction is assisted by sterically hindered amines and catalytic amounts of thioureas. According to computational studies the reaction proceeds via frustrated Lewis pair (FLP) mechanism. The obtained aryldifluoroboranes are further stabilized against destructive protodeborylation by converting them to the corresponding air stable tetramethylammonium organotrifluoroborates.

Indole-3-carbonitriles as DYRK1A inhibitors by fragment-based drug design

Meine, Rosanna,Becker, Walter,Falke, Hannes,Preu, Lutz,Loa?c, Nadège,Meijer, Laurent,Kunick, Conrad

Dual-specificity tyrosine phosphorylation-regulated kinase 1A (DYRK1A) is a potential drug target because of its role in the development of Down syndrome and Alzheimer's disease. The selective DYRK1A inhibitor 10-iodo-11H-indolo[3, 2-c]quinoline-6-carboxy

On water phosphine-free palladium-catalyzed room temperature C-H arylation of indoles

Islam, Saidul,Larrosa, Igor

supporting information, p. 15093 - 15096 (2013/11/06)

Get on top of your chemistry! An "on water", palladium-catalyzed, phosphine-free direct C-H arylation of indoles, with iodoarenes at 25-30°C, is disclosed (see scheme; TBDMS=N-tert-butyldimethylsilyl ether; SEM=N-2-(trimethylsilyl)ethoxymethyl; Bn=benzyl, Piv=pivabyl). The mildness of the reaction conditions permits the tolerance of a variety of N1-protected indoles.
