147189-98-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 147189-98-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,1,8 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 147189-98:
(8*1)+(7*4)+(6*7)+(5*1)+(4*8)+(3*9)+(2*9)+(1*8)=168
168 % 10 = 8
So 147189-98-8 is a valid CAS Registry Number.

Enantioselective syntheses of (+)-sertraline and (+)-indatraline using lithiation/borylation-protodeboronation methodology

Roesner, Stefan,Casatejada, Javier Mansilla,Elford, Tim G.,Sonawane, Ravindra P.,Aggarwal, Varinder K.

, p. 5740 - 5743 (2011/12/22)

The lithiation/borylation-protodeboronation of a homoallyl carbamate was applied to the synthesis of (+)-sertraline and (+)-indatraline. Due to the presence of the alkene, significant modifications of the methodology were required (use of 12-crown-4, TMSCl, H2O), or a solvent switch to CHCl3, to achieve high yields and high selectivities.

Synthesis of 4(S)-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone by SN2 cuprate displacement of an activated chiral benzylic alcohol

Quallich,Woodall

, p. 10239 - 10248 (2007/10/02)

Two routes for the preparation of 4(S)-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone are reported. The most efficient route generates a chiral benzylic alcohol by catalytic asymmetric oxazaborolidine reduction of a γ-ketoester that is subsequently activated and displaced in an SN2 manner with a higher order cuprate. Intramolecular Friedel-Crafts cyclization of the resulting t-butylester affords the title compound.
