D-(+)-Threonine (HD-Thr-OH) (CAS: 632-20-2) est D-forma Threoninae, quae genus amino acida est.Ad praeparationem enantiomerice pura 1,3-butanediol adhiberi potest.Usurpatur etiam ut medius in praeparatione compositorum chiralium ut antibioticorum.D-Threonina est efficax stagnum chiralum gerens, quod continet extra centrum stereo-sum.Exempli causa, homines recenter ea usi sunt ut principium materiae ad summam synthesim acidi legionaminici custoditi.D-Threonine isomer innaturalis est L-Threonine et inhibere incrementum et murum cellarium Mycobacterium smegmatis notum est.D-Threonine etiam media synthetica adhibetur ad antibioticos chiralis producendos.Productio methodus DL-Threonine adhibetur ut materia rudis cum Chloroacetyl Chloride sub conditionibus alkalinis, postquam retrahitur sub pressura reducta, productus cum acetone extractus et tandem ab acylase I resolvitur.
