    2). Acid-induced rearrangement of 4 led to the formation of the corresponding 4-hydroxybenzo[a]heptalene-2,3-dicarboxylates 5 in moderate-to-good yields (Schemes 8, 13, and 14). When the aromatization reaction is performed in the presence of trifluoroacetic acid (TFA), trifluoroacetates of type 6 and 13 (Schemes 8, 12, and 13) are also formed via deprotonation of the intermediate tropylium ions of

    A novel approach towards the synthesis of functionalized benzo[a]heptalenes 9 and 10 via a 6 6pi-electrocyclic ring closure - aromatization sequence of corresponding bis[prop-2-enoates] 5 and 6 has been developed (Scheme 1). The starting bis[prop-2-enoates] have been prepared from the corresponding dialdehydes 3a and 4a in a Wittig-Horner reaction, and their UV/VIS properties have also been investigated (Fig. I and Table 1). The dehydrogenations of the corresponding diols I and 2 to dialdehydes with a number of oxidizing reagents, including MnO2 in CH2Cl2, tetrapropylammonium perruthenate (TPAP), and activated DMSO, have been studied in detail.

The further way, to get finally the benzo[a]heptalene 13b with MeO groups in 1,2,3-position, could not be realized due to the fact that we found no way to cleave the carbamate group of 2,3-endo-(P*)-10b without touching its 1,4-epoxy bridge
