58745-46-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 58745-46-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,7,4 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 58745-46:
(7*5)+(6*8)+(5*7)+(4*4)+(3*5)+(2*4)+(1*6)=163
163 % 10 = 3
So 58745-46-3 is a valid CAS Registry Number.

Directing Group in Decarboxylative Cross-Coupling: Copper-Catalyzed Site-Selective C-N Bond Formation from Nonactivated Aliphatic Carboxylic Acids

Liu, Zhao-Jing,Lu, Xi,Wang, Guan,Li, Lei,Jiang, Wei-Tao,Wang, Yu-Dong,Xiao, Bin,Fu, Yao

supporting information, p. 9714 - 9719 (2016/08/11)

Copper-catalyzed directed decarboxylative amination of nonactivated aliphatic carboxylic acids is described. This intramolecular C-N bond formation reaction provides efficient access to the synthesis of pyrrolidine and piperidine derivatives as well as the modification of complex natural products. Moreover, this reaction presents excellent site-selectivity in the C-N bond formation step through the use of directing group. Our work can be considered as a big step toward controllable radical decarboxylative carbon-heteroatom cross-coupling.

Improved protocol for indoline synthesis via palladium-catalyzed intramolecular C(sp2)-H amination

He, Gang,Lu, Chengxi,Zhao, Yingsheng,Nack, William A.,Chen, Gong

supporting information; experimental part, p. 2944 - 2947 (2012/08/28)

An efficient method has been developed for the synthesis of indoline compounds from picolinamide (PA)-protected β-arylethylamine substrates via palladium-catalyzed intramolecular amination of ortho-C(sp2)-H bonds. These reactions feature high efficiency, low catalyst loadings, mild operating conditions, and the use of inexpensive reagents.
