1239897-00-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1239897-00-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,8,9 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1239897-00:
(9*1)+(8*2)+(7*3)+(6*9)+(5*8)+(4*9)+(3*7)+(2*0)+(1*0)=197
197 % 10 = 7
So 1239897-00-7 is a valid CAS Registry Number.

A comparative study on the acylative kinetic resolution of racemic fluorinated and non-fluorinated 2-methyl-1,2,3,4-tetrahydroquinolines and 3,4-dihydro-3-methyl-2H-[1,4]benzoxazines

, p. 1240 - 1246 (2013/10/22)

The acylative kinetic resolution of racemic 6-fluoro-2-methyl-1,2,3,4- tetrahydroquinoline, 7,8-difluoro-3,4-dihydro-3-methyl-2H-[1,4]benzoxazine, and their non-fluorinated analogues with (S)-naproxen and N-phthaloyl-(S)-amino acyl chlorides has been carried out. It has been shown that the presence of fluorine atoms in the aromatic fragment of a heterocyclic amine results in the increasing stereoselectivity of acylation with (S)-naproxen acyl chloride and in a decrease in the efficiency of acylative kinetic resolution using N-phthaloyl-(S)-amino acyl chlorides. A method for the preparation of enantiopure (S)-6-fluoro-2-methyl-1,2,3,4-tetrahydroquinoline (ee >99%) was developed.

Synthesis of enantiomers of 6-nitro-and 6-amino-2-methyl-1,2,3,4- tetrahydroquinolines

, p. 748 - 757 (2012/11/07)

Enantiomers of 2-methyl-6-nitro-1,2,3,4-tetrahydroquinoline have been obtained by kinetic resolution of racemic 2-methyl-1,2,3,4-tetrahydroquinoline in acylation with acyl chlorides of N-protected amino acids followed by regioselective nitration of the di

Acylative kinetic resolution of racemic amines using N-phthaloyl-(S)-amino acyl chlorides

Gruzdev, Dmitry A.,Levit, Galina L.,Krasnov, Victor P.,Chulakov, Evgeny N.,Sadretdinova, Liliya Sh.,Grishakov, Aleksandr N.,Ezhikova, Marina A.,Kodess, Mikhail I.,Charushin, Valery N.

experimental part, p. 936 - 942 (2010/08/19)

A comparative study of the kinetic resolution of racemic 2-methyl-1,2,3,4-tetrahydroquinoline and 2,3-dihydro-3-methyl-4H-1,4-benzoxazine using N-phthaloyl-(S)-amino acyl chlorides as chiral acylating agents is described. Temperature and solvent effects on the stereochemical features have been examined. It has been found that N-phthaloyl-(S)-phenylalanyl and N-phthaloyl-(S)-2-phenylglycyl chlorides bearing aromatic substituents close to the stereogenic centre are more stereoselective acylating agents than N-phthaloyl-(S)-alanyl chloride. For the preparative kinetic resolution of racemic amines N-phthaloyl-(S)-phenylalanyl chloride proved to be the most appropriate chiral acylating agent.
