3731-51-9 Usage
Description
It is usually used as the intermediate or raw material in the organic synthesis and pharmaceutical synthesis. For example, this chemical can promote the Al(OTf)3-catalyzed aminolysis of 1,2-epoxides to produce β-Amino alcohols N-2'-pyridylmethyl in excellent yields.1 Moreover, this substance may function as the raw material to produce copper(Ⅱ) complexes with sulfonamides that act as the active chemical nucleases.2 In addition, by using this chemical as substrate, an efficient [2+3] cycloaddition approach has been developed for the synthesis of pyridyl-appended fullerene ligands.3 Besides, 2-picolylamine is chosen as the recognition group to get better selectivity for a rhodamine-based “turn-on” fluorescent probe for Fe3+ in aqueous solution.4

Check Digit Verification of cas no
The CAS Registry Mumber 3731-51-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,3 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3731-51:
(6*3)+(5*7)+(4*3)+(3*1)+(2*5)+(1*1)=79
79 % 10 = 9
So 3731-51-9 is a valid CAS Registry Number.

Direct Conversion of Hydrazones to Amines using Transaminases
Carter, Eve M.,Hailes, Helen C.,Sheppard, Tom D.,Subrizi, Fabiana,Ward, John M.
, p. 4520 - 4523 (2021/09/20)
Transaminase enzymes (TAms) have been widely used for the amination of aldehydes and ketones, often resulting in optically pure products. In this work, transaminases were directly reacted with hydrazones in a novel approach to form amine products. Several substrates were investigated, including those with furan and phenyl moieties. It was determined that the amine yields increased when an additional electrophile was added to the reaction mixture, suggesting that they can sequester the hydrazine released in the reaction. Pyridoxal 5’-phosphate (PLP), a cofactor for transaminases, and polyethylene glycol (PEG)-aldehydes were both found to increase the yield of amine formed. Notably, the amination of (S)-(?)-1-amino-2-(methoxymethyl)pyrrolidine (SAMP) hydrazones gave promising results as a method to form chiral β-substituted amines in good yield.

Paragraph 0067-0071, (2020/12/09)
The invention relates to a half-sandwiched ruthenium complex containing a carborane schiff base ligand and a preparation and an application thereof. The preparation method specifically comprises the following steps; i) dissolving o-carborane formaldehyde and aromatic amine in an organic solvent, carrying out reaction at 60-100 DEG C for 8-12h, cooling to room temperature after the reaction; ii) adding n-butyllithium, carrying out reaction at room temperature for 1.5-2.5h; ii) adding phellandrene ruthenium chloride dimer, carrying out reaction at room temperature for 3-6h, and obtaining the half-sandwiched ruthenium complex through separation. The half-sandwiched ruthenium complex is applied to catalyze transfer hydrogenation reaction of nitrile compounds. Compared with the prior art, the complex of the present invention is not sensitive to air and water, has stable properties, and shows high-efficiency catalytic activity in catalyzing the transfer hydrogenation reaction of nitrile compounds. The preparation method of the complex is simple and green, high in yield, mild in reaction conditions and good in universality.
