Direct reversed-phase high-performance liquid chromatographic methods were developed for the separation of enantiomers of β-lactams. The enantiomers of 7 aryl-substituted β-lactams were separated on chiral stationary phases containing the macrocyclic glycopeptide antibiotic teicoplanin (Chirobiotic T) and teicoplanin aglycone (Chirobiotic TAG) at 10-°C increments in the range 5–45 °C, using different...
Direct reversed-phase high-performance liquid chromatographic methods were developed for the separation of the enantiomers of tricyclic β-lactams, cis-3,4-benzo-6-azabicyclo[3.2.0]heptan-7-one, cis-4,5-benzo-7-azabicyclo[4.2.0]-octan-8-one, cis-5,6-benzo-8-azabicyclo[5.2.0]nonan-9-one and new bicyclic β-amino acids, the six- and seven-membered homologues of cis-1-amino-4,5-benzocyclopentane-2-carboxylic...
