Embodiment Construction

[0188] The present invention is further described in detail with reference to the following examples, which are not intended to limit the scope of the invention claimed in the claims in any way.

[0189] General Notes: All reactions involving air-sensitive reagents or intermediates were performed under nitrogen with anhydrous reagents. Magnesium sulfate was used as a drying agent in the work-up procedure, and the solvent was evaporated under reduced pressure.

[0190] Method A

[0191] (±)-3-(Naphthalen-2-yloxy)-1-aza-bicyclo[2.2.2]octane fumarate

[0192] (Compound A1)

[0193] To 2-naphthol (5.0 g, 34.5 mmol), (±)-3-quinuclidinol (guinuclidinol) (2.94 g, 23.1 mmol), triphenylphosphine (9.0 g, 34.5 mmol) and THF (100 mL) was added to the mixture: diethyl azodicarboxylate (5.4 mL, 34.5 mmol) was added over 30 minutes at room temperature. The reaction mixture was stirred at 50 °C for 20 hours. Aqueous sodium hydroxide solution (100 mL, 1M) was added. The mixture w...

Abstract

This invention relates to novel quinuclidine derivatives and their use as pharmaceuticals. Due to their pharmacological profile the compounds of the invention may be useful for the treatment of diseases or disorders as diverse as those related to the cholinergic system of the central nervous system (CNS), the peripheral nervous system (PNS), diseases or disorders related to smooth muscle contraction, endocrine diseases or disorders, diseases or disorders related to neuro-degeneration, diseases or disorders related to inflammation, pain, and withdrawal symptoms caused by the termination of abuse of chemical substances.

Description

technical field [0001] The present invention relates to novel quinucidine derivatives and their use as medicines. Due to their pharmaceutical properties, the compounds of the present invention can be used in the treatment of diseases or conditions associated with the cholinergic system of the central nervous system (CNS), peripheral nervous system (PNS), diseases or conditions associated with smooth muscle contraction, endocrine diseases or conditions, diseases or conditions associated with neurodegeneration, diseases or conditions associated with inflammation, pain, and withdrawal symptoms associated with cessation of chemical substance abuse. technical background [0002] The endogenous cholinergic neurotransmitter acetylcholine expresses its biological effects through two types of cholinergic receptors, the muscarinic acetylcholine receptors (mAChR) and the nicotinic acetylcholine receptors (nAChR). [0003] It is well established that muscarinic acetylcholine receptors ...
