The regio- and stereochemistry of electrophile-promoted transannular ring expansion of cyclo 1,5- and 1,6-epoxyalkenes and cyclo trans-1,5-bisepoxides were studied.The results are rationalized in terms of tricyclic oxonium intermediates showing the directing ability of oxygen substituents in the regio- and stereocontrol observed.
