General Description

Optically active building block.

Check Digit Verification of cas no

The CAS Registry Mumber 21210-43-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,1 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21210-43:
(7*2)+(6*1)+(5*2)+(4*1)+(3*0)+(2*4)+(1*3)=45
45 % 10 = 5
So 21210-43-5 is a valid CAS Registry Number.

Catalytic enantioselective O-H insertion reactions

Maier, Thomas C.,Fu, Gregory C.

, p. 4594 - 4595 (2006)

The first effective method for catalytic enantioselective insertions into O-H bonds has been developed. Specifically, a copper/bisazaferrocene catalyst couples alcohols such as 2-trimethylsilylethanol with α-aryl-α-diazo esters in high yield and good ee.

A Unified Strategy for the Asymmetric Synthesis of Highly Substituted 1,2-Amino Alcohols Leading to Highly Substituted Bisoxazoline Ligands

Shrestha, Bijay,Rose, Brennan T.,Olen, Casey L.,Roth, Aaron,Kwong, Adon C.,Wang, Yang,Denmark, Scott E.

, p. 3490 - 3534 (2021/02/16)

A general procedure for the asymmetric synthesis of highly substituted 1,2-amino alcohols in high yield and diastereoselectivity is described that uses organometallic additions of a wide range of nucleophiles to tert-butylsulfinimines as the key step. The addition of organolithium reagents to these imines follows a modified Davis model. The diastereoselectivity for this reaction depends significantly on both the nucleophile and electrophile. These highly substituted 1,2-amino alcohols are used to synthesize stereochemically diverse and structurally novel, polysubstituted 2,2′-methylene(bisoxazoline) ligands in high yields.

Biocatalysed reductions of α-ketoesters employing CyreneTM as cosolvent

de Gonzalo, Gonzalo

, (2021/02/26)

The search for novel reaction media with environmental friendly properties is an area of great interest in enzyme catalysis. Water is the medium of biocatalysed processes, but due to its properties, sometimes the presence of organic (co)solvents is required. CyreneTM represents one of the newest approaches to this medium engineering. This polar solvent has been employed for the first time in biocatalysed reductions employing purified alcohol dehydrogenases. A set of α-ketoesters has been reduced to the corresponding chiral α-hydroxyesters with high conversions and optical purities, being possible to obtain good results at Cyrene contents of 30% v/v and working at substrate concentrations of 1.0 M in presence of 2.5% v/v of this solvent. At this concentration, the presence of Cyrene has a beneficial effect in the bioreduction conversion.
