17605-71-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17605-71-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,0 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17605-71:
(7*1)+(6*7)+(5*6)+(4*0)+(3*5)+(2*7)+(1*1)=109
109 % 10 = 9
So 17605-71-9 is a valid CAS Registry Number.

Enantioselective and Diastereoselective Construction of Chiral Amino Alcohols by Iridium-f-Amphox-Catalyzed Asymmetric Hydrogenation via Dynamic Kinetic Resolution

Wu, Weilong,You, Cai,Yin, Congcong,Liu, Yuanhua,Dong, Xiu-Qin,Zhang, Xumu

, p. 2548 - 2551 (2017/05/24)

The iridium-f-amphox-catalyzed asymmetric hydrogenation of racemic α-amino β-unfunctionalized ketones proceeds via a DKR (dynamic kinetic resolution) process for the construction of various chiral N,N-disubstituted α-amino β-unfunctionalized alcohols in quantitative yields with excellent enantioselectivities and diastereoselectivities (all products >99% ee and >99:1 dr, TON up to 100 000). Importantly, this catalytic asymmetric hydrogenation with a DKR process provided a highly efficient and powerful synthetic strategy for the preparation of key chiral intermediates of the preclinical antitumor agent (S,S)-R116010.

Dynamic resolution of α-bromo-α-alkyl esters using N-methyl pseudoephedrine as a chiral auxiliary: Asymmetric syntheses of α-amino acid derivatives

Lee, Sang-Kuk,Nam, Jiyoun,Yong, Sun Park

, p. 790 - 792 (2007/10/03)

N-Methyl pseudoephedrine mediated dynamic resolution of α-bromo-α-alkyl esters in nucleophilic substitution reaction has been investigated. Best results are obtained when α-bromo-α-alkyl esters 1, 4 and 5 are allowed to equilibrate before the addition of nucleophile. This simple epimerization-substitution sequence provides a practical protocol for asymmetric syntheses of α-amino acid derivatives 2, 7 and 8 up to 98:2 enantiomeric ratio.
