  • or
(R)-2-Methylpyrrolidine hydrochloride is a chemical compound that belongs to the azacyclic compounds class, specifically a pyrrolidine, which is a five-membered ring structure with four carbon atoms and one nitrogen atom. It is the hydrochloride salt form of this compound, which provides improved stability and higher solubility in water or other polar solvents, making it more suitable for reactions or processes. As an optically active substance, it exhibits chirality, meaning it exists in two enantiomeric forms that are mirror images of each other. This property is of particular interest in the pharmaceutical industry for the production of drugs with specific and selective activities.

Check Digit Verification of cas no

The CAS Registry Mumber 135324-85-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,2 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 135324-85:
(8*1)+(7*3)+(6*5)+(5*3)+(4*2)+(3*4)+(2*8)+(1*5)=115
115 % 10 = 5
So 135324-85-5 is a valid CAS Registry Number.

Asymmetric synthesis of chiral cyclic amine from cyclic imine by bacterial whole-cell catalyst of enantioselective imine reductase

Mitsukura, Koichi,Suzuki, Mai,Tada, Kazuhiro,Yoshida, Toyokazu,Nagasawa, Toru

, p. 4533 - 4535 (2010)

Streptomyces sp. GF3587 and 3546 were found to be imine-reducing strains with high R- and S-selectivity by screening using 2-methyl-1-pyrroline (2-MPN). Their whole-cell catalysts produced 91 mM R-2-methylpyrrolidine (R-2-MP) with 99.2%e.e. and 27.5 mM S-2-MP (92.3%e.e.) from 2-MPN at 91-92% conversion in the presence of glucose, respectively.

An efficient and convergent synthesis of the potent and selective H3 antagonist ABT-239

Ku, Yi-Yin,Pu, Yu-Ming,Grieme, Tim,Sharma, Padam,Bhatia, Ashok V.,Cowart, Marlon

, p. 4584 - 4589 (2007/10/03)

An efficient and convergent process for the preparation of a potent and selective H3 receptor antagonist, ABT-239, 1A was accomplished with an overall yield of 64%. The key step in the synthesis is a Sonogashira coupling/cyclization reaction of 1-but-3-ynyl-2-(R)-methylpyrrolidine (9) with 4′-hydroxy-3′-iodo-biphenyl-4-carbonitrile (3). Additionally, the key amine component 2-(R)-methylpyrrolidine (7) was effectively synthesized from the readily available Boc-l-prolinol with a simple catalytical hydrogenolysis as the key step. This column chromatography-free process is highlighted by several simple work-up and purification procedures and is amendable to the large-scale preparation of 1A.
