(2R,3R)-2-Phenyl-5-p-tolyl-pyrrolidine-2,3-dicarboxylic acid dimethyl ester is a complex organic compound with the molecular formula C20H23NO4. It is a chiral molecule, meaning it has a non-superimposable mirror image, and it is a derivative of pyrrolidine, a heterocyclic compound with a nitrogen atom in a four-membered ring. The compound features a phenyl group at the 2-position and a p-tolyl group at the 5-position, which are both aromatic rings. The 2,3-dicarboxylic acid part of the name indicates the presence of two carboxylic acid groups at the 2 and 3 positions of the pyrrolidine ring. The dimethyl ester part signifies that the carboxylic acid groups are esterified with methanol, making the compound a diester. This specific configuration of the molecule, with the R-enantiomer at both the 2 and 3 positions, is important for its stereochemistry and potential biological activity.

Check Digit Verification of cas no

The CAS Registry Mumber 75524-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,2 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 75524-21:
(7*7)+(6*5)+(5*5)+(4*2)+(3*4)+(2*2)+(1*1)=129
129 % 10 = 9
So 75524-21-9 is a valid CAS Registry Number.

X=Y-ZH SYSTEMS AS POTENTIAL 1,3-DIPOLES. THE STEREOCHEMISTRY AND REGIOCHEMISTRY OF CYCLOADDITION REACTIONS OF IMINES OF α-AMINO-ACID ESTERS.

Grigg, Ronald,Kemp, James

, p. 2461 - 2464 (2007/10/02)

The stereochemistry and regiochemistry of cycloadditions of α-amino acid ester imines is dependent both on imine structure and on the reactivity of the dipolarophile.Phenylglycine imines undergo competing dipole stereomutation and cycloaddition with some dipolarophiles.
