The enantiomeric resolution of chiral sulfoxides was investigated on a
mylose (S)-alpha-methylbenzyl carbamate phase coated on aminopropylate
d 7 mu m silica with 500 Angstrom diameter pores. This was shown to be
very successful in the separation of alkyl/aryl, aryl/aryl, and non-a
romatic sulfoxides. The effect of pore size using naked silica was als
o investigated, demonstrating that the pore size does not affect the r
esolution. (C) 1996 Wiley-Liss, Inc.
