Application:

D-2-Aminobutyric Acid (H-D-Abu-OH) (CAS: 2623-91-8) is an isomer of L-Aminobutyric Acid.
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%.
Use: D-2-Aminobutyric Acid is used as a pharmaceutical intermediate
