Photoinduced electron transfer (PET) reactions of α-cyclopropyl-substituted ketones and triethylamine (TEA) were used to initiate the cyclopropylcarbinyl-homoallyl rearrangement. The intramolecular cyclization reaction onto triple bonds was performed yielding bicyclic and spirocyclic compounds. Furthermore, in some preliminary studies it was shown that even intramolecular aromatic substitutions are

chosen as a point of departure for the design of 4(5)-[(3,4-dihydro-2-naphthalenyl)methyl]-4,5-dihydroimidazole (4a), which displayed the desired profile: alpha(2A)-adrenoceptor antagonist properties and serotonin/noradrenaline uptake inhibition. From this original molecule, a series of derivatives was designed and synthesized, encompassing substituted as well as rigid analogues. Structure-activity relationships
