The acid catalysed rearrangement of asperulosidol 5 leads to the tetracyclic acetal 7 whose structure and configuration has been determined by 1H-NMR and 13C-NMR spectroscopy as well as by the Li/NH3 reduction of 7 to the cyclopententriol 10.The reaction course has been clarified by reacting 5 with DCl and formation of the monodeutero derivative 9.
