916525-59-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 916525-59-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,5,2 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 916525-59:
(8*9)+(7*1)+(6*6)+(5*5)+(4*2)+(3*5)+(2*5)+(1*9)=182
182 % 10 = 2
So 916525-59-2 is a valid CAS Registry Number.

Application of meso-hydrobenzoin-derived chiral auxiliaries for the stereoselective synthesis of highly substituted pyrrolidines by 1,3-dipolar cycloaddition of azomethine ylides

Bica, Katharina,Gaertner, Peter

scheme or table, p. 641 - 646 (2010/08/03)

The metal-catalyzed stereoselective 1,3-dipolar cycloaddition of azomethine ylides and acrylates using recyclable meso-hydrobenzoin-derived chiral auxiliaries is described. Cleavage of the auxiliary leads to highly substituted pyrrolidines in up to 87% en

Chiral linker. Part 3: Synthesis and evaluation of aryl substituted m-hydrobenzoins as solid supported open chain chiral auxiliaries for the diastereoselective reduction of α-keto esters

Broeker, Joachim,Knollmueller, Max,Gaertner, Peter

, p. 2413 - 2429 (2007/10/03)

Five partly novel aryl substituted m-hydrobenzoins were synthesized and the corresponding desymmetrized hydrobenzoin ethers evaluated as open chain chiral auxiliaries in the L-Selectride mediated stereoselective reduction of phenylglyoxylates, resulting in de values of up to 91%. Two optimized auxiliary structures were immobilized on commercially available Wang-resin and applied as a reusable solid supported chiral auxiliary in the same type of reaction.
