P. Koll et A. Lutzen, RESOLUTION OF RACEMIC CARBOXYLIC AND SULFONIC-ACIDS VIA D-XYLOSE DERIVED NEW CYCLIC CARBAMATE REAGENTS (OXAZOLIDIN-2-ONES), Tetrahedron : asymmetry, 6(1), 1995, pp. 43-46
Two new chiral oxazolidin-2-ones have been easily prepared from D-xylo
se and studied as chiral derivatizing agents (CDA's) for the resolutio
n of racemic carboxylic and sulfonic acids The resultant diastereomers
are readily separated by chromatographic methods and easily hydrloyze
d to isolate the resolved materials in high optical purities and to re
turn the CDA's for reuse.
