A number of tetrahydrofuran analogues of 2'-methylspiro[1-azabicyclo[2.2.2]octane-3,4'-[1,3]dioxolane] ( 1) have been prepared with the aim to obtain information about the relative importance of each of the oxygens in 1 for efficacy and for selectivity. In addition, the dimethyl and deamethyl doguea of 1 &re prepared. The new compounds were compared to cis- and trans-1 with regard to their ability to displace (-)-[3H]-3-quinuclidinyl benzilate ((-)-[3H]QNB) from muscarinic receptors in cerebral cortex, heart, parotid gland, and urinary bladder from guinea pigs. Functioinal studies were made on isolated guinea pig bladder and ileum. The new compounds exhibited both lower affmity and efficacy thancis-1.Aconformational studywasperformed,and the effects of steric and electronic factors on the biological activity of the compounds are discussed.
