A series of achiral 3-heteroaryl substituted quinuclidin-2-ene derivatives and related compounds have been synthesized by facile methods. The compounds were evaluated for muscarinic and antimuscarinic properties in receptor binding studies using (-)-[H-3]-QNB as the radioligand and ina functional assay using isolated guinea pig urinary bladder. 3-(2-Benzofuranyl)-quinuclidin-2-ene (15) displayed the highest M(1)-receptor affinity in the present series (K-i = 9.6 nM).
