494836-60-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 494836-60-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,4,8,3 and 6 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 494836-60:
(8*4)+(7*9)+(6*4)+(5*8)+(4*3)+(3*6)+(2*6)+(1*0)=201
201 % 10 = 1
So 494836-60-1 is a valid CAS Registry Number.

Two concise total syntheses of the wasabi phytoalexin methyl 1-methoxyindole-3-carboxylate

Li, Bing,Williams, John D.,Peet, Norton P.

, p. 3124 - 3126 (2013)

Two new syntheses of the phytoalexin methyl 1-methoxyindole-3-carboxylate (1) were developed that employ the same key intermediate. Methyl 2-(2-nitrophenyl)acrylate (2) was directly converted into phytoalexin 1 using modified Cadogan-Sundberg indole synth

Discovery of 3,3′-Spiro[Azetidine]-2-oxo-indoline Derivatives as Fusion Inhibitors for Treatment of RSV Infection

Shi, Weihua,Jiang, Zhigan,He, Haiying,Xiao, Fubiao,Lin, Fusen,Sun, Ya,Hou, Lijuan,Shen, Liang,Han, Lixia,Zeng, Minggao,Lai, Kunmin,Gu, Zhengxian,Chen, Xinsheng,Zhao, Tao,Guo, Li,Yang, Chun,Li, Jian,Chen, Shuhui

supporting information, p. 94 - 97 (2018/02/19)

A new series of 3,3′-spirocyclic-2-oxo-indoline derivatives was synthesized and evaluated against respiratory syncytial virus (RSV) in a cell-based assay and animal model. Extensive structure-activity relationship study led to a lead compound 14h, which e

Aqueous Titanium Trichloride Promoted Reductive Cyclization of o-Nitrostyrenes to Indoles: Development and Application to the Synthesis of Rizatriptan and Aspidospermidine

Tong, Shuo,Xu, Zhengren,Mamboury, Mathias,Wang, Qian,Zhu, Jieping

supporting information, p. 11809 - 11812 (2015/10/05)

Treatment of o-nitrostyrenes with aqueous TiCl3 solution at room temperature afforded indoles through a formal reductive C(sp2)-H amination process. A range of functions such as halides (Cl, Br), carbonyl (ester, carbamate), cyano, hydroxy, and amino groups were tolerated. From β,β-disubstituted o-nitrostyrenes, 2,3-disubstituted indoles were formed by a domino reduction/cyclization/migration process. Mild conditions, simple experimental procedure, ready accessibility of the starting materials and good to excellent yields characterize the present transformation. The methodology was used as a key step in a concise synthesis of rizatriptan and a formal total synthesis of aspidospermidine. Mild and efficient treatment of o-nitrostyrenes with aqueous TiCl3 solution at room temperature afforded indoles through a formal reductive C(sp2)-Hamination process. A concise synthesis of a marketed drug (rizatriptan) and a formal total synthesis of aspidospermidine featuring this novel N-heterocyclization process are reported.
