The present invention relates to novel spiro-oxadiazoline compounds that are suitable as agonists or partial agonists of a7-nAChR, and pharmaceutical compositions of the same, methods of preparing these compounds and compositions, and the use of these compounds and compositions in methods of maintaining, treating and/or improving cognitive function. In particular, methods of administering a spiro-oxadiazoline cx7-nAChR agonist or partial agonist, to a patient in need thereof, for example a patient with a cognitive deficiency and/or a desire to enhance cognitive function, that may derive a benefit therefrom.

A fast, efficient, and general method for the preparation of highlyfluorescentderivatives containing the pyrrolopyridazine moiety by microwave irradiation is reported. The first synthesis of pyrrolopyridazine derivatives using non-symmetrically substituted alkynes and alkenes by microwave and classical heating is also reported.

irradiation, in liquid phase, is reported. Under MW irradiation the yields are much higher, sometimes substantially (by almost double) and, the amount of solvent used is at least 5-fold less. The pyrrolopyridazine (PP) derivatives are very intense blue emitters and have high quantum yields (up to 90%) while pyrrolophthalazine (PHP) compounds are still intense blue emitters but the quantum yield is negligible
decreased considerably and the amount of solvents used was reduced substantially. Consequently, the microwaveassisted alkylation of N-containing heterocycles could be considered eco-friendly. In some cases, under MW irradiation the yields are also higher. A comparative study of microwave vs. classical conditions (liquid solvents) has been done. Twelve new diazaheterocylic salts of potential practical
