Description and Uses

D-threonine 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 (T405500) 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. It is a steroisomer of the proteinogenic amino acid L-threonine. It has the potential to treat hypostatic leg ulceration.
