Abstract
Di-trans-1,2:3,4-dibenzo[7,8-c]furo[10]annulene (VI) and di-trans- 1,2:3,4-dibenzo-7,8-(3?,6?-epoxy-4?,5?- dimethoxycarbonyl)cyclo- hexeno[10]annulene (VII) have been synthesized. As a result of the steric interference of the internal hydrogen atoms, the former compound could be separated into two conformational isomers. Neither (VI) nor (VII) possessed a delocalized ten π-electron system.https://doi.org/10.1071/CH9691449
