Check Digit Verification of cas no

The CAS Registry Mumber 68968-12-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,9,6 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 68968-12:
(7*6)+(6*8)+(5*9)+(4*6)+(3*8)+(2*1)+(1*2)=187
187 % 10 = 7
So 68968-12-7 is a valid CAS Registry Number.

Development of a Robust and Highly Selective Ru(II)-Catalyzed Dynamic Kinetic Resolution Used to Manufacture AMG 232

Bio, Matthew M.,Caille, Seb,Colyer, John T.,Diker, Khalid,Gorins, Gilles,Jones, Sian C.,Silva Elipe, Maria,Smith, Austin G.,Tedrow, Jason S.,Walker, Shawn D.

, p. 1164 - 1174 (2020/07/16)

We describe herein the development of a scalable Noyori reductive dynamic kinetic resolution to manufacture DLAC, a ? -lactone precursor to the active pharmaceutical ingredient AMG 232. Central to this work was the identification of the ruthenabicyclic complex RuCl[(S)-daipena][(S)-xylBINAP] ((S)-RUCY-xylBINAP), which afforded the product with >98:2 enantiomeric ratio at a substrate to catalyst loading (S/C) of 2000:1. By transesterification to a more sterically hindered isopropyl ester prior to the hydrogenation, we were able to curb unexpected ester reduction. Optimization of base equivalents in the final alkylation step to form DLAC prevented product degradation. The optimized process was scaled to >200 kg, providing 147 kg of DLAC in 56percent overall yield with 99.9percent optical purity.

Discovery of a small molecule MDM2 inhibitor (AMG 232) for treating cancer

Rew, Yosup,Sun, Daqing

, p. 6332 - 6341 (2014/09/30)

We recently reported the discovery of AMG 232 (1), a potent and selective piperidinone inhibitor of the MDM2-p53 protein-protein interaction. Compound 1 is currently being evaluated in human clinical trials for the treatment of cancer. This article provides an overview of its discovery from the de novo design of the piperidinone series to the structure-activity studies leading to the identification of 1. In addition, this article also describes the preclinical pharmacology and pharmacokinetics of 1, along with its drug metabolism and safety assessment.

An expeditious synthesis of the MDM2-p53 inhibitor AM-8553

Lucas, Brian S.,Fisher, Benjamin,McGee, Lawrence R.,Olson, Steven H.,Medina, Julio C.,Cheung, Eugene

supporting information; experimental part, p. 12855 - 12860 (2012/09/22)

The development of the structurally complex MDM2/p53 inhibitor AM-8553 was impeded by the low yield of the initial synthesis. A second generation synthesis is described that features a Noyori dynamic kinetic resolution, a highly diastereoselective allylation, and a novel oxazoline-assisted piperidinone forming reaction to provide AM-8553 in 35.6% yield and 11 steps.

Structure-based design of novel inhibitors of the MDM2-p53 interaction

Rew, Yosup,Sun, Daqing,Gonzalez-Lopez De Turiso, Felix,Bartberger, Michael D.,Beck, Hilary P.,Canon, Jude,Chen, Ada,Chow, David,Deignan, Jeffrey,Fox, Brian M.,Gustin, Darin,Huang, Xin,Jiang, Min,Jiao, Xianyun,Jin, Lixia,Kayser, Frank,Kopecky, David J.,Li, Yihong,Lo, Mei-Chu,Long, Alexander M.,Michelsen, Klaus,Oliner, Jonathan D.,Osgood, Tao,Ragains, Mark,Saiki, Anne Y.,Schneider, Steve,Toteva, Maria,Yakowec, Peter,Yan, Xuelei,Ye, Qiuping,Yu, Dongyin,Zhao, Xiaoning,Zhou, Jing,Medina, Julio C.,Olson, Steven H.

experimental part, p. 4936 - 4954 (2012/08/07)

Structure-based rational design led to the discovery of novel inhibitors of the MDM2-p53 protein-protein interaction. The affinity of these compounds for MDM2 was improved through conformational control of both the piperidinone ring and the appended N-alkyl substituent. Optimization afforded 29 (AM-8553), a potent and selective MDM2 inhibitor with excellent pharmacokinetic properties and in vivo efficacy.

Preparation of functionalized organomanganese(II) reagents by direct insertion of manganese to aromatic and benzylic halides

Peng, Zhihua,Knochel, Paul

supporting information; experimental part, p. 3198 - 3201 (2011/08/06)

Functionalized arylmanganese compounds were prepared using commercial manganese powder in the presence of LiCl and catalytic amounts of both 2.5% InCl3 and 2.5% PbCl2 (THF, 0-50 °C). In addition, benzylic manganese reagents are obtained at 25 °C in ca. 70-80% yield (in the absence of LiCl) using commercial manganese powder and catalytic amounts of 2.5% InCl3 and 2.5% PbCl2. The resulting organomanganese reagents undergo smooth 1,2-addition, acylation, allylic substitution, Pd-catalyzed cross-coupling, and copper-catalyzed conjugate addition, affording the desired products in good yields.
