The following chiral pyrrolidine derivatives, 7-substituted (2R,5S)-2- aryl-1-aza-3-oxabicyclo[3.3.0]octan-8-ones (18-24), 7-substituted (2R,5S)-2- aryl-1-aza-3-oxabicyclo[3.3.0]oct-6-en-8-ones (25-29) and 3-substituted (S)- 5-(hydroxymethyl)-2-pyrrolidinones (30-34), were synthesized starting from (S)-pyroglutamic acid and their absolute configurations were determined based on their 1H-NMR spectra.
