RESUMO
Treatment of selected (4 + 3) cycloadducts derived from oxidopyridinium ions with N-iodosuccinimide (NIS) in hexafluoroisopropanol (HFIP) resulted in the formation of bridgehead ethers via a net oxidative C-H activation.

RESUMO
Easily prepared cycloadducts derived from the (4+3) cycloaddition of oxidopyridinium ions with dienes reacted intramolecularly in a [2+2] cycloaddition process to afford complex polycyclic species in which the tropane skeleton was embedded.
