The first synthesis of bicyclic ortho-quinodimethanes from tricyclic sulfone precursors has been achieved. The required sulfones, 3,4,5,6-tetrahydro-1H-cyclohex[cd]benzothiophene-2,2-dioxide and 1,3,4,5,6,7-hexahydrocyclohept[cd]benzothiophene-2,2-dioxide, were prepared from α-tetralone and benzosuberone utilizing a ring closure proceeding through a sulfonium salt intermediate. The same strategy failed
