The crystal structure analysis was done using single crystal X-ray diffraction method. In both the compounds, the trimethylsilyloxy- and naphthaquinone/ N-benzylmaleimide moieties are endo- to the bicyclic ring. Graphical Abstract The synthesis of two novel trimethylsilyloxy- substituted bicyclo[2.2.2]octene derivatives by employing ultrasonic reaction conditions is reported. The compounds have been characterized by single crystal X-ray studies.
