65417-74-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 65417-74-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,4,1 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 65417-74:
(7*6)+(6*5)+(5*4)+(4*1)+(3*7)+(2*7)+(1*4)=135
135 % 10 = 5
So 65417-74-5 is a valid CAS Registry Number.

Palladium-Catalyzed α-Arylation of Silylenol Ethers in the Synthesis of Isoquinolines and Phenanthridines

Saini, Gaurav,Kumar, Pravin,Kumar, Gangam Srikanth,Mangadan, Arun Raj Kizhakkayil,Kapur, Manmohan

supporting information, p. 441 - 444 (2018/01/28)

A diverse array of isoquinolines and phenanthridines have been accessed by developing a two-step, one-pot method constituting regioselective palladium-catalyzed Kuwajima-Urabe α-arylation of silylenol ethers and acid-mediated deprotection, annulation, and aromatization. Structural diversity in the silylenol ethers leads to three different classes of isoquinolines and phenanthridines from which related natural products can be derived. The synthetic utility of this method by the quick assembly of the natural product trispheridine is also demonstrated.

Catalytic asymmetric transformations with fine-tunable biphenol-based monodentate ligands

Chapsal, Bruno D.,Hua, Zihao,Ojima, Iwao

, p. 642 - 657 (2007/10/03)

A library of new fine-tunable monodentate phosphite and phosphoramidite ligands based on chiral biphenol have been designed and developed. These monodentate phosphorus ligands have exhibited excellent enantioselectivity in the Pd-catalyzed asymmetric allylic alkylation and Rh-catalyzed asymmetric hydrogenation.
