Intermolecular (4+3) cycloaddition reactions: Anthracene and its derivatives as dienes

Abstract

The (4+3)cycloaddition reactions of allylic cations to dienes is a powerful method for the direct synthesis of sevenmembered rings which are occurrence in many of natural products have biological activity. (4+3) cycloadditions reactions between oxyallyl cations and anthracene or 9-substituted anthracene have not yet been studied extensively. Although these compounds have great importance, where 9,10-dihydro-9,10-propano-anthraceness can be used as key step in the medicinal synthesis. For this reason In this review article we will emphasis on the reactions between anthracene and its derivatives as dienes with α,α'-dihaloketones and α,α,α',α'-tetrahaloketones as oxyallyl cations.
