5-disubstituted quinuclidines were obtained stereoselectively from 4-bromoacetylpiperidine (7) to give (1a) and (1b) (9:1) or by Dieckmann cyclisation of piperidine (9) to give ketals (13a) and (13b) (9:1). Pyrrolidine triester (14) gave exclusively the -1-azanorbornane ester (15a). Epimerisation of (13a) and (15a) gave (13b) and (15b) respectively as the thermodynamic products.

A class of novel oxadiazoles, substituted on one of the ring carbon atoms with a non-aromatic azacyclic or azabicyclic ring, and substituted on the other ring carbon atom with a substituent of low lipophilicity; are potent muscarinic agonists, and have good CNS penetrability. The compounds are therefore useful in the treatment of neurological and mental illnesses.
