tandem cycloaddition reactions with high stereoselectivity. The reaction of bisfurans with dimethyl acetylenedicarboxylate (DMAD) involves tandem [4 + 2]/[4 + 2] cycloadditions in a pincer mode. The reaction of oligofurans with arynes involves stereoselective tandem [4 + 2]/[4 + 2] cycloaddition reactions in a domino mode. The corresponding aryne adducts have been transformed into extended perylene derivatives

Four new polycyclic aromatic hydrocarbons containing seven fusedrings have been synthesized and their properties described. The spectral data relating to the new compounds are discussed and Clar's principles of annelation have been applied to substantiate the assigned structures.
