Hansen, H J; El Rayes, S; Linden, Anthony; Abou-Hadeed, K (2011). Nucleophilic reactions of 9-Isopropyl-2,4-dimethoxy-7,12-dimethyl-3-(phenylsulfonyl)benzo[a]heptalene with Lithium Dialkylamides. Heterocycles, 82(2):1195-1202.
Treatment of the title compounds with lithium piperidinide in THF at –5 °C leads to an exchange of the two methoxy groups by piperidino substituents (Scheme 2). On the other hand, lithium diisopropylamide (LDA) in THF at –5 °C induces the formation heptaleno-annulated dibenzothiophenes.
