133271-00-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 133271-00-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,2,7 and 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133271-00:
(8*1)+(7*3)+(6*3)+(5*2)+(4*7)+(3*1)+(2*0)+(1*0)=88
88 % 10 = 8
So 133271-00-8 is a valid CAS Registry Number.

Highly efficient enzymatic resolution of homoallyl alcohols leading to a simple synthesis of optically pure fluoxetine and related compounds

Master, Hosang E.,Newadkar,Rane,Kumar, Ashok

, p. 9253 - 9254 (1996)

A practical method for enzymatic resolution of homoallyl alcohols and its utility in the synthesis of optically pure fluoxetine and related compounds is reported.

A site isolation-enabled organocatalytic approach to enantiopure γ-amino alcohol drugs

Wang, Shoulei,Rodríguez-Escrich, Carles,Fan, Xinyuan,Pericàs, Miquel A.

supporting information, p. 3943 - 3946 (2018/04/20)

Solid support-enabled site isolation has previously allowed to use paraldehyde as an acetaldehyde surrogate in aldol reactions. However, only electron-poor aldehydes were tolerated by the system. Herein, we show that the temporary conversion of benzaldehyde into η6-benzaldehyde Cr(CO)3 circumvents this limitation. Asymmetric synthesis of (R)-Phenoperidine, as well as formal syntheses of (R)-Fluoxetine and (R)-Atomoxetine, illustrate the benefits of this strategy.

A diarylprolinol in an asymmetric, catalytic, and direct crossed-aldol reaction of acetaldehyde

Hayashi, Yujiro,Itoh, Takahiko,Aratake, Seiji,Ishikawa, Hayato

supporting information; experimental part, p. 2082 - 2084 (2009/02/06)

(Chemical Equation Presented) No over-reacting: A diarylprolinol was found to be an effective organocatalyst of the direct, enantioselective aldol reaction of acetaldehyde, affording β-hydroxy α-unsubstituted aldehydes in good yield with excellent enantio
