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.

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.

The reactions of monomeric C,N-chelated organogermanium(II) hydride L(H)Ge?BH3 with organolithium salts RLi yielded lithium hydrogermanatoborates (Li(THF)2{BH3[L(H)GeR]})2. Compound (Li(THF)2{BH3[L(H)GePh]})2 was used as a source of LiH for the reduction of organic C=O or C=N bonds in nonpolar solvents accompanied by the elimination of a neutral complex L(Ph)Ge?BH3. The interaction of (Li(THF)2{BH3[L(H)GePh]})2 with the polar C=O bond was further investigated by computational studies revealing a plausible geometry of a pre-reactive intermediate. The experimental and theoretical studies suggest that, although the Li atom of (Li(THF)2{BH3[L(H)GePh]})2 coordinates the C=O bond, the GeH fragment is the active species in the reduction reaction. Finally, benzaldehyde was reduced by a mixture of L(H)Ge?BH3 with PhLi in nonpolar solvents.
