Check Digit Verification of cas no

The CAS Registry Mumber 863301-32-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,3,3,0 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 863301-32:
(8*8)+(7*6)+(6*3)+(5*3)+(4*0)+(3*1)+(2*3)+(1*2)=150
150 % 10 = 0
So 863301-32-0 is a valid CAS Registry Number.

Catalytic Asymmetric Synthesis of Chiral 2-Vinylindole Scaffolds by Friedel-Crafts Reaction

Arai, Takayoshi,Tsuchida, Akiko,Miyazaki, Tomoya,Awata, Atsuko

, p. 758 - 761 (2017)

A chiral bis(imidazolidine)pyridine (PyBidine)-Ni(OTf)2 complex smoothly catalyzed an asymmetric Friedel-Crafts reaction of 2-vinylindoles with nitroalkenes to give chiral indoles in a highly enantioselective manner while maintaining the 2-vinyl functionality. The chiral 2-vinylindoles offer unique chiral scaffolds for diverse transformations.

Enantioselective Friedel-Crafts alkylation of indole with nitroalkenes in the presence of bifunctional squaramide organocatalysts

Dündar, Esra,Tanyeli, Cihangir

supporting information, (2021/05/26)

A series of chiral bifunctional quinine and 2-aminoDMAP based squaramide organocatalysts are evaluated in Friedel-Crafts alkylation of indoles with nitroolefins. These 3-substituted indole derivatives are synthesized in the presence of sterically encumber

Asymmetric Ruthenium-Catalyzed Hydrogenation of Terpyridine-Type N-Heteroarenes: Direct Access to Chiral Tridentate Nitrogen Ligands

Li, Chenghao,Pan, Yixiao,Feng, Yu,He, Yan-Mei,Liu, Youran,Fan, Qing-Hua

supporting information, p. 6452 - 6457 (2020/08/24)

The first enantioselective hydrogenation of terpyridine-type N-heteroarenes has been successfully developed by using Ru(diamine) complexes as catalysts, providing partially reduced chiral pyridine-amine-type products in high yield (up to 93%) with excellent diastereo- and enantioselectivity (up to 94:6 dl/meso, > 99% ee). These pyridine-amine-type compounds can be served as a new class of chiral multidentate nitrogen-donor ligands, which were successfully applied to the Cu-catalyzed asymmetric Friedel-Crafts alkylation reaction of indoles with nitroalkenes.

A chiral bicyclic skeleton-tethered bipyridine-Zn(OTf)2 complex as a Lewis acid: Enantioselective Friedel-Crafts alkylation of indoles with nitroalkenes

Venkatanna, Kesa,Yeswanth Kumar, Santhakumar,Karthick, Muthupandi,Padmanaban, Ramanathan,Ramaraj Ramanathan, Chinnasamy

, p. 4077 - 4086 (2019/04/30)

A conformationally rigid chiral bicyclic skeleton tethered bipyridine-Zn(OTf)2 complex facilitated the enantioselective Friedel-Crafts alkylation of indoles with trans-β-nitroarylalkenes in an enantioselective manner at elevated temperature. Indoles reacted smoothly with β-nitroarylalkenes to generate the corresponding 3-(2-nitroalkyl)indoles in good to excellent yields (up to 94%) with moderate to excellent enantioselectivities (up to 91%). The stereochemical outcome of the product from indole and trans-β-nitrostyrene in the presence of the CRCB tethered bipyridine-Zn(OTf)2 complex and the DFT calculation of the CRCB tethered bipyridine-Zn:trans-β-nitrostyrene complex support the si-face attack of indole on trans-β-nitrostyrene.
