Compositions for enhancing memory of a subject comprising a combination of a positive modulator of an AMPA receptor and a positive modulator of an NMDA receptor are provided, wherein each modulator of the combination is present at a subtherapeutic dose for effecting memory enhancement. Methods for using such compositions in the treatment of cognitive impairment associated with aging, age-related diseases, and CNS disorders, for example, are provided. New fusion molecules are also provided that combine the positive modulator functionalities into one molecule.

The reaction of N-(3-phenylpropionyloxy)phthalimide (1a) and N-tosyloxy (5a,b) derivatives with nucleophiles was examined and found to give the products via Lossen-type rearrangement. In order to obtain the scope of this reaction mechanism, further studies the reaction of several N-sulfonyloxyimide derivatives with various nucleophiles under similar conditions were carried out and found to afford the
