摘要：

A one pot synthesis gives methyl-5,6,7,8-tetrahydrodinaphtho[1,2-b:2',1'-d]thiophenes (7) from methyl-1,2,3,4-tetrahydronaphthalen-1-ones (1) by bromination and sufurization. Tetrahydro compounds 7 have been dehydrogenated to corresponding dinaphtho[b,d]thiophenes 8. Proofs for the constitutions are nmr data of 7, 8 and the independent synthesis of one compound 8. A reaction mechanism with 1,4-dithiine intermediates is discussed.
