Discovery of Novel 1-Azoniabicyclo[2.2.2]octane Muscarinic Acetylcholine Receptor Antagonists
摘要:
A novel 4-hydroxyl(diphenyl)methyl substituted quinuclidine series was discovered as a very promising class of muscarinic antagonists. The structure-activity relationships of the connectivity of the diphenyl moiety to the quinuclidine core and around the ring nitrogen side chain are described. Computational docking studies using an homology model of the M-3 receptor readily explained the observed structure-activity relationship of the various compounds. Compound 14o was identified as a very potent, slowly reversible M-3 antagonist with a very long in vivo duration of bronchoprotection.

An N-heterocyclic carbene catalyzed remote C(sp3)−H acylation of amides was developed, and also combined with a cascade cyclization. Over 120 functionalized δ-amino ketones and isoquinolinones with diverse substituents were synthesized in up to 99 % yield under mild conditions. Preliminary mechanistic investigations shed light on the organocatalytic radical reaction mechanism.
