3-Methylaspartic acid, also known as β-methylaspartic acid, is a naturally occurring non-proteinogenic amino acid. It is structurally similar to aspartic acid, with the key difference being the presence of a methyl group (-CH3) attached to the β-carbon atom. 3-Methylaspartic acid is found in various biological systems, including some plants and microorganisms, and plays a role in certain metabolic processes. 3-Methylaspartic acid is also used in scientific research to study enzyme specificity and as a chiral building block in the synthesis of pharmaceuticals and other organic compounds. Its chemical formula is C5H9NO4, and it has a molecular weight of 147.13 g/mol.

6667-60-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6667-60-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,6 and 7 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6667-60:
(6*6)+(5*6)+(4*6)+(3*7)+(2*6)+(1*0)=123
123 % 10 = 3
So 6667-60-3 is a valid CAS Registry Number.

Indium-mediated allylation and Reformatsky reaction on glyoxylic oximes under ultrasound irradiation

Soengas, Raquel G.,Estévez, Amalia M.

experimental part, p. 916 - 920 (2012/06/04)

A novel and more convenient method for the indium-promoted allylation of glyoxylic oximes based on the use of ultrasonic waves is reported. A similar procedure was used to develop the first example reported in the literature of an indium-mediated Reformatsky reaction on oxime ethers.

Organocatalytic synthesis of β-alkylaspartates via β-lactone ring opening

Armstrong, Alan,Geldart, Stephen P.,Jenner, Chloe R.,Scutt, James N.

, p. 8091 - 8094 (2008/02/13)

(Chemical Equation Presented) Cinchona alkaloid-catalyzed reaction of ethyl glyoxylate with substituted ketenes, formed in situ, gives disubstituted β-lactones in moderate yield and high enantiomeric excess. Subsequent azide ring opening, reduction, and e

FLAME-INDUCED CARBOXYLATION OF UNSATURATED AMINES IN AN AQUEOUS FORMIC ACID SOLUTION

Nomoto, Shinya,Harada, Kaoru

, p. 145 - 148 (2007/10/02)

When a hydrogen-oxygen flame was kept in contact with an aqueous formic acid solution of unsaturated amines, carboxylation onto a double bond took place.This reaction revealed to be initiated by addition of a hydrogen atom to the double bond followed by coupling of the resulted substrate radical with a carboxyl radical.

SYNTHESIS AND ABSOLUTE STEREOCHEMISTRY OF SERRICORNIN

Mori, Kenji,Nomi, Hiroko,Chuman, Tatsuji,Kohno, Masahiro,Kato, Kunio,Noguchi, Masao
