Abstract
Several methodologies for the generation of oxyallyl cations from polybromoketones and other substrates are discussed. The mechanistic aspect of the [3+4] cycloaddition reaction between these cations and dienes leading to the formation of seven membered ring carbocyclic compounds is presented. Finally, some synthetic applications of the [3+4] cycloaddition are shownKeywords
