1007893-74-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1007893-74-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,7,8,9 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1007893-74:
(9*1)+(8*0)+(7*0)+(6*7)+(5*8)+(4*9)+(3*3)+(2*7)+(1*4)=154
154 % 10 = 4
So 1007893-74-4 is a valid CAS Registry Number.

A cascade coupling strategy for one-pot total synthesis of β-carboline and isoquinoline-containing natural products and derivatives

Zhu, Yan-Ping,Liu, Mei-Cai,Cai, Qun,Jia, Feng-Cheng,Wu, An-Xin

, p. 10132 - 10137 (2013)

Multi-birds with one stone: A cascade coupling strategy was developed for the synthesis of β-carbolines. The method can direct the synthesis of β-carboline and isoquinoline-containing natural products with high yields. Moreover, this protocol can also be further applied towards the total synthesis of natural products fascaplysin and papaverin (see scheme). Copyright

Iodine-mediated oxidative Pictet-Spengler reaction using terminal alkyne as the 2-oxoaldehyde surrogate for the synthesis of 1-aroyl-β-carbolines and fused-nitrogen heterocycles

Dighe, Shashikant U.,Samanta, Surya K.,Kolle, Shivalinga,Batra, Sanjay

, p. 2455 - 2467 (2017/04/03)

An efficient iodine-mediated oxidative Pictet-Spengler reaction in dimethyl sulphoxide (DMSO) using terminal alkynes as the 2-oxoaldehyde surrogate for the synthesis of aryl (9H-pyrido[3,4-b]indol-1-yl)methanones is described. The scope of the protocol includes the total synthesis of Fascaplysin, Eudistomins Y1 and Y2. The methodology is extended for preparing pyrrolo[1,2-a]-quinoxaline and indolo[1,5-a]quinoxaline derivatives. The utility of 1-aroyl-β-carbolines was demonstrated by performing palladium-catalyzed β-carboline directed ortho-C(sp2)-H functionalization of the phenyl ring with thiomethyl (SMe) group using DMSO as source and for accessing 4-aryl-canthin-6-ones.

Total synthesis and biological activity of marine alkaloid eudistomins Y1-Y7 and their analogues

Jin, Huijuan,Zhang, Puyong,Bijian, Krikor,Ren, Sumei,Wan, Shengbiao,Alaoui-Jamali, Moulay A.,Jiang, Tao

Eudistomin Y class compounds are a series of β-carbolines which was originally isolated from a marine turnicate or ascidian near the South Korea Sea. These compounds contain bromo-substituted groups, which is one of the typical characters of marine natural products. We report herein the chemical synthesis and biological evaluation of seven new β-carboline-based metabolites, Eudistomins Y1-Y7, and their hydroxyl-methylated phenyl derivatives. Using bromo-substituted tryptamines and bromo-substituted phenylglyoxals as the key intermediates, Eudistomins Y 1-Y7 and their derivatives were synthesized via the acid-catalyzed Pictet-Spengler reaction and fully characterized by 1H- and 13C-NMR and mass spectroscopy. Biological studies revealed that all of the compounds showed moderate growth inhibitory activity against breast carcinoma cell line MDA-231 with IC50 of 15-63 μM and the inhibitory activities of hydroxyl-methylated phenyl products were higher than that of the corresponding natural products Eudistomins Y 1-Y7.
