Chiral amines play an important role in stereoselective organic synthesis. They are used directly as resolving agents, building blocks or chiral auxiliaries.

Check Digit Verification of cas no

The CAS Registry Mumber 181657-57-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,6,5 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 181657-57:
(8*1)+(7*8)+(6*1)+(5*6)+(4*5)+(3*7)+(2*5)+(1*7)=158
158 % 10 = 8
So 181657-57-8 is a valid CAS Registry Number.

Hybrid Organo- and Biocatalytic Process for the Asymmetric Transformation of Alcohols into Amines in Aqueous Medium

Liardo, Elisa,Ríos-Lombardía, Nicolás,Morís, Francisco,Rebolledo, Francisca,González-Sabín, Javier

, p. 4768 - 4774 (2017/07/24)

A hybrid organo- and biocatalytic system for the asymmetric conversion of racemic alcohols into amines was developed. Combining an organocatalyst, AZADO, an oxidant, NaOCl, and an enzyme, ω-transaminase, we implemented a one-pot oxidation-transamination sequential process in aqueous medium. The method showed broad substrate scope and was successfully applied to conventional secondary alcohols and sterically hindered β-substituted cycloalkanols, where a highly stereoselective dynamic asymmetric bioamination enabled us to set up both contiguous stereocenters with very high enantio- and diastereomeric ratio (>90% yield, >99% ee, and up to 49:1 dr).
