Wh. Pirkle et We. Bowen, PREPARATIVE SEPARATION OF ENANTIOMERS USING HOLLOW-FIBER MEMBRANE TECHNOLOGY, Tetrahedron : asymmetry, 5(5), 1994, pp. 773-776
Several chromatographically developed chiral selectors show promise fo
r large scale separation of enantiomers using hollow-fiber membrane te
chnology. Chiral selectors derived from N(1-naphthyl)leucine have been
used in a hollow-fiber membrane system (Sepracor) to separate the ena
ntiomers of amino acid derivatives. Enantiomeric purities exceeding 95
% have been obtained in a single pass through the system For data coll
ection, sample sizes were limited to gram quantities of racemate.
