Application:

D-(+)-Threonine (H-D-Thr-OH) (CAS: 632-20-2) is the D-form of Threonine, which is a kind of amino acids. It can be used for the preparation of enantiomerically pure 1,3-butanediol. It is also used as the intermediate during the preparation of chiral compounds such as antibiotics. D-Threonine is an effective chiral pool reagent which contains an extra stereo-center. For example, people has recently used it as the starting material for total synthesis of protected legionaminic acid. D-Threonine is the unnatural isomer of L-Threonine and is known to inhibit growth and cell wall synthesis of Mycobacterium smegmatis. D-Threonine is also used as a synthetic intermediate for the production of chiral antibiotics. Production method DL-Threonine is used as the raw material to react with Chloroacetyl Chloride under alkaline conditions, after concentration under reduced pressure, the product was extracted with acetone and finally resolved by acylase I.
