  Synthese von Benzo[b]thioxanthenen

  摘要：

  Benzo[b]thioxanthenes, heterocyclic compounds related to tetracenes and tetracyclines can be obtained by the reaction of 2H-benzo[b]thiete (1) and 1,4-naphthoquinones (3a-g). The primary cycloadducts 4a-g undergo an autoxidation process leading to the quinones 6a-g. The dihydroxy compound 4e shows an additional isomerization by a tetra-fold H transfer (4e --> 5e'). Another preparative route to benzo[b]thioxanthenes makes use of the cycloadditon reaction of 1 and 1,4-epoxynaphthalenes (7a-d). The primary adducts can be transformed to the title compounds by catalytic dehydration processes (8a-d --> 9a-d). An alternate regioselective opening of the oxygen bridge can be performed by the action of trimethyliodosilane (8a --> 10a). Methylation of 9a furnishes the sulfonium salt 14a which rearranges in a strongly alkaline medium to 16a; in the presence of oxygen ketone 17a is generated.
