Popis:	The cycloaddition of the bisdienophile 1 and the benzo[c]furan generated in situ from the precursor 2 yielded the nonaphene derivative 4 (Scheme 1). A related reaction (Scheme 3) was used for the preparation of the dithianonaphene systems 6a, b, c, namely the [2π+8π] cycloaddition of 1 and 2H-benzothiete (5/5′). Acidic dehydration (aromatization) of 6a, b, c led to the dithianonaphenes 7a, b, c (Scheme 4).
