The DTBB-catalyzed lithiation of 4-hetero-substituted dibenzothiins (phenoxathiin, phenothiazine, and thianthrene) gives the corresponding functionalized organolithium intermediates, which by reaction with different electrophiles afford the expected functionalized thiols. The cyclization of some alcohol compound derivatives gives the corresponding homologous seven-membered dibenzo heterocycles.
