Abstract

Enantiomers of 19 racemic β-lactams, with 3 and 4-position substitutions, were separated using gas chromatography. Excellent results were achieved on derivatized cyclodextrin-based GC chiral stationary phases (CSPs). All 19 compounds were baseline separated, most with high resolution factors. The Chiraldex G-TA was found to be the most powerful CSP with the broadest enantioselectivity, while Chiraldex B-DM produced the fastest separations for most of the compounds assayed. Results obtained in this work suggest that GC can serve as a potential method for the enantiomeric separation of sufficiently volatile solid β-lactams.
