In one aspect, the invention relates to substituted 5-aminothieno[2,3-c]pyridazine-6- carboxamide analogs, derivatives thereof, and related compounds, which are useful as positive allosteric modulators of the muscarinic acetylcholine receptor M4 (mAChR M4); synthesis methods for making the compounds; pharmaceutical compositions comprising the compounds; and methods of treating neurological and psychiatric disorders associated with muscarinic acetylcholine receptor dysfunction using the compounds and compositions. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

Sterically congested 1-azabicyclo[1.1.0]butanes 1 add hydrazoicacid smoothly at 0–5°, giving 3-azidoazetidines 2 in good to excellent yields. After hydrogenolysis over Pd/C catalyst, compounds 2 were converted into N-unsubstituted azetidin-3-amines 4. Attempted reduction of 2a with Raney-Ni led to a mixture of the expected azetidin-3-amine 4a and the ring-enlarged 2,5-dihydro-1H-imidazole derivative
