Novel, selective M-2 muscarinic antagonists, which replace the metabolically labile styrenyl moiety of the prototypical M-2 antagonist 1 with an ether linkage, were synthesized. A detailed SAR study in this class of compounds has yielded highly active compounds that showed M-2 K-i values of < 1.0 nM and > 100-fold selectivity against M-1, M-3, and M-5 receptors.
