aprotic media yields superoxide anions O2.−. These highly reactiveradicalanions easily attack sensitive arenes. It is, therefore, not possible to generate the radicalanions of anthracene-9-carboxylic esters (1) by direct in situ electroreduction. Because derivatives substituted in the 10-position are stable against these radicals, indirect generation of the radicalanion 1.− was realized in order to

9-(Pent-4-yn-1-yl)anthracene-type compounds can potentially undergo intramolecular Diels-Alder (IMDA) reaction to form 9,11-annulated dibenzobarrelenes. Herein we report the synthesis and IMDA reactions of several heteroatom incorporated 9-(pent-4-yn-1-yl)anthracene-type compounds.
