New enantiomerically pure 3-naphthylaminomethylpyrrolidines (8), (9), (14) and (15) were obtained through simple steps starting from chiral 4- ethenylpyrrolidin-2-ones (2) and (3). On the other hand, starting from pyrrolidine (16), an epimerisation reaction occurred, which was explained through formation of the bicyclic ammonium salt (18). Nucleophilic addition of Et2Zn to benzaldehyde, carried out in the presence of 8, gave (S)-1- phenyl-1-propanol in 28% e.e.
