Abstract:

The 2,3-Diaryl-2-azabicyclooctanones derivatives (1) can be synthetized by Povarov Multicomponent Reaction (MCR) using a Lewis Acid as reaction promoter. The Povarov MCRs are defined as a process in which three or more reagents are combined in the same reaction “pot” generating the products with good structural complexity, with characteristics of each reagent used and in a single step. In studies recently found in the literature, we can observe the good applicability of 2,3-Diaryl-2- azabicyclooctanones derivatives as possible drugs for the treatment of Alzheimers’s disease. The azabicyclooctanones derivatives act by inhibiting the acetylcholinesterase (AChE), an enzyme responsible by the hydrolysis of acetylcholine in the brain. In this work we report a new method to synthesize 2,3-Diaryl-2-azabicyclooctanones derivatives through Povarov MCRs, using niobium pentaethoxide as a reaction promoter.
