227319-36-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 227319-36-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,3,1 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 227319-36:
(8*2)+(7*2)+(6*7)+(5*3)+(4*1)+(3*9)+(2*3)+(1*6)=130
130 % 10 = 0
So 227319-36-0 is a valid CAS Registry Number.

Catalytic asymmetric oxidative carbonylation-induced kinetic resolution of sterically hindered benzylamines to chiral isoindolinones

Mu, Qiu-Qi,Nie, Yi-Xue,Li, Hang,Bai, Xing-Feng,Liu, Xue-Wei,Xu, Zheng,Xu, Li-Wen

, p. 1778 - 1781 (2021/02/27)

A highly enantioselective kinetic resolution of sterically hindered benzylamines has been achieved for the first time through transition-metal-catalyzed oxidative carbonylation, in which the new KR strategy offered a new approach to afford chiral isoindolinones (er up to 97?:?3) and the origin of chemoselectivity and stereoselectivity was confirmed by density functional theory (DFT) calculations.

Effect of the 4′-substituted phenylalanine moiety of sansalvamide A peptide on antitumor activity

Liu, Shouxin,Yang, Yihua,Zhao, Cuiran,Huang, Jing,Han, Chunyu,Han, Jianrong

, p. 463 - 467 (2014/04/17)

Eight sansalvamide A peptide analogues with 4′-fluoride, 4′-chloride, 4′-bromide, 4′-iodide, and 4′- methoxyphenylalanine moieties were synthesized. The effect of these para-substitutions of sansalvamide A peptide on their cytotoxicity was evaluated using HCT-116, MDA-MB-231, HT-29, HCT-15, K562, HeLa, and A549 cell lines. The 4′-methoxyphenylalanine analog of sansalvamide A peptide was found to be a promising antitumor agent.

Practical, catalytic enantioselective hydrogenation to synthesize N -unprotected β-amino esters

Matsumura, Kazuhiko,Zhang, Xiaoyong,Hori, Kiyoto,Murayama, Toshiyuki,Ohmiya, Tadamasa,Shimizu, Hideo,Saito, Takao,Sayo, Noboru

experimental part, p. 1130 - 1137 (2012/01/03)

Practical and simple catalytic enantioselective hydrogenation reactions to synthesize N-unprotected β-amino esters have been developed: (1) asymmetric hydrogenation of N-unprotected β-enamine ester and (2) asymmetric direct reductive amination of β-keto esters using ammonium salts. A Ru-DM-SEGPHOS complex was used as the catalyst in both cases and gave high enantioselectivity, high reactivity, and wide substrate applicability. These protocols greatly reduced reaction time and waste compared to conventional synthetic routes. The direct reductive amination route was demonstrated on a >100 kg scale.
