149218-98-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 149218-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,2,1 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 149218-98:
(8*1)+(7*4)+(6*9)+(5*2)+(4*1)+(3*8)+(2*9)+(1*8)=154
154 % 10 = 4
So 149218-98-4 is a valid CAS Registry Number.

Dearomative Indole (3 + 2) Reactions with Azaoxyallyl Cations - New Method for the Synthesis of Pyrroloindolines

DiPoto, Maria C.,Hughes, Russell P.,Wu, Jimmy

supporting information, p. 14861 - 14864 (2015/12/08)

Herein, we report the first examples of the synthesis of pyrroloindolines by means of (3 + 2) dearomative annulation reactions between 3-substituted indoles and highly reactive azaoxyallyl cations. Computational studies using density functional theory (DFT) (B3LYP-D3/6-311G++) support a stepwise reaction pathway in which initial C-C bond formation takes place at C3 of indole, followed by ring closure to give the observed products. Insights gleaned from these calculations indicate that the solvent, either TFE or HFIP, can stabilize the transition state through H-bonding interactions with oxygen of the azaoxyallyl cation and other relevant intermediates, thereby increasing the rates of these reactions.

Synthesis of Novel HMG-CoA Reductase Inhibitors, II. Heterocyclic Analogs of Mevinolin

Novak, Lajos,Hornyanszky, Gabor,Rohaly, Janos,Kolonits, Pal,Szantay, Csaba

, p. 1877 - 1884 (2007/10/03)

The indole (1) and chroman analogs (2) of mevinolin and their 6S diastereomers 15c and 25d were synthesized in several steps starting with methyl (R)-3--4-formylbutyrate (12) and 2-(indol-3-yl)ethanol (3) or 6-methoxychroman-4-one (16), respectively.Compounds 1 and 2 inhibited moderately the HMG-CoA reductase.The diastereomers 15c and 25d were shown to be inactive. - Keywords: HMG-CoA reductase inhibitors / 3-Indolylheptanoates and -acetates / 4-Chromanylheptanoates and -acetates
