摘要：

Thianthrene-5-oxide (1) reacted with 2.2 equivalents of lithium diisopropylamide to give 4,6-dilithiated 1 which was converted to 4,6-disubstituted thianthrene-5-oxides (3). 3 afforded sterically crowded 1,9-disubstituted dibenzothiophenes (4) in moderate yields on treatment with n-butyllithium or phenyllithium.
