b-Lactam (±)-N-benzyl-4-phenyl-azetidin-2-one rac-6a was converted into the g-lactam (±)-trans-4,5-diphenyl-pyrrolidin-2-one rac-5 which was resolved via the preparation of diastereomers with N-phthalyl-L-alanine chloride or D-alanine chloride and its absolute configuration was determined by X-ray c

The enantiodiscriminating potential of the weak anion exchange-type quinine-based chiral stationary phases (CSPs) for direct enantiomer separation of racemic 2-methoxy-2-(1-naphthyl)propionic acid (selectand, SA) was studied. The influence of structure variations of the selector (SO) in the carbamat
## Abstract An efficient enantioselective synthesis of 3‐acetoxy __trans__‐__β__‐lactams **7a** and **7b** __via__ [2+2] cycloaddition reactions of imines **4a** and **4b**, derived from a polycyclic aromatic amine and bicyclic chiral acid obtained from (+)‐car‐3‐ene, is described. The cycloadditio
