A lipase-catalyzed enantioselective esteri®cation process in cyclohexane was developed for the synthesis of S( )-naproxen ester prodrugs containing the moiety of N,N-dialkylamino, ethylene glycol or alkyl ether of ethylene glycol. A high enantiomeric ratio of 44 was obtained when di(ethylene glycol
