The synergistic effect of TiO2nanotubes and ultrasonication in promoting efficient synthesis of tacrine derivatives from 2-amino-3-cyanopyridine and cyclic ketones at room temperature was investigated. In this synthesis, the synergistic effect between Lewis acid and base sites on TiO2nanotubes and intercalation of reactants as guest molecules into TiO2nanotubes as host nanoreactors promoted by ultrasonication
