D-ALPHA-AMINO-N-BUTYRIC ACID - Reference Information
| introduction | D-2-aminobutyric acid is an amino acid derivative and can be used as a biochemical reagent. |
| application | D-2-aminobutyric acid is a key intermediate of chiral drugs, chiral pesticides and chiral food additives, and is widely used in the fields of medicine, pesticides and food. D-2-aminobutyric acid is an important unnatural chiral α-amino acid. It is an important chemical raw material and chiral intermediate, and is widely used in drug synthesis. |
| synthesis method | at present, the literature reports on the synthesis of D-2-aminobutyric acid, such as using methionine in d configuration as raw material to synthesize D-2-aminobutyric acid through desulfurization and other steps. Ammonia hydrolysis reaction method, chemical separation method, etc. First, the racemic 2-aminobutyric acid is acetylated to obtain N-acetyl-2-aminobutyric acid, and then the amino acylase extracted from the pig kidney is used to selectively hydrolyze the (S)-configuration N-Acetyl-2-aminobutyric acid, thereby obtaining (S)-2-aminobutyric acid, the unhydrolyzed (R)-N-acetyl -2-aminobutyric acid was racemized by an appropriate method to obtain racemic 2-aminobutyric acid, thus realizing its dynamic kinetic resolution and its final yield reaching 71.9%. |
| biological activity | D(-)-2-Aminobutyric acid is a pharmaceutical intermediate. |
| Use | Used as a pharmaceutical intermediate |
