D-2-Aminobutyric Acid (HD-Abu-OH) (CAS: 2623-91-8) yog ib qho isomer ntawm L-Aminobutyric Acid.
Taw qhia: D-2-Aminobutyric Acid yog ib qho amino acid derivative thiab tuaj yeem siv los ua biochemical reagent.
Daim ntawv thov: D-2-Aminobutyric Acid yog ib qho tseem ceeb nruab nrab ntawm chiral tshuaj, chiral tshuaj tua kab thiab chiral zaub mov additives, thiab yog dav siv nyob rau hauv cov tshuaj, tshuaj tua kab thiab zaub mov.D-2-Aminobutyric Acid yog ib qho tseem ceeb unnatural chiral α-amino acid.Nws yog ib qho tseem ceeb tshuaj raw khoom thiab chiral intermediate, thiab yog dav siv nyob rau hauv tshuaj synthesis.
Synthesis method: Tam sim no, cov ntaub ntawv qhia txog kev sib txuas ntawm D-2-Aminobutyric Acid, xws li siv methionine hauv d configuration raws li raw khoom los ua ke D-2-Aminobutyric Acid los ntawm desulfurization thiab lwm cov kauj ruam.Ammonia hydrolysis tshuaj tiv thaiv txoj kev, tshuaj cais txoj kev, thiab lwm yam. Ua ntej, cov racemic 2-Aminobutyric Acid yog acetylated kom tau N-Acetyl-2-Aminobutyric Acid, thiab ces cov amino acylase muab rho tawm los ntawm lub raum npua yog siv los xaiv hydrolyze lub (S )-configuration N-Acetyl-2-Aminobutyric Acid, yog li tau txais (S)-2-Aminobutyric Acid, unhydrolyzed (R)-N-Acetyl -2-Aminobutyric Acid yog racemized los ntawm ib txoj kev tsim nyog kom tau racemic 2-Aminobutyric Acid , yog li paub txog nws qhov kev daws teeb meem kinetic thiab nws cov txiaj ntsig kawg ncav cuag 71.9%.
Kev Siv: D-2-Aminobutyric Acid yog siv los ua tshuaj nruab nrab
