Regiospecific Synthesis of Benzo[b]fluorenones via Ring Contraction by Benzil-Benzilic Acid Rearrangement of Benz[a]anthracene-5,6-diones

Regiospecific Synthesis of Benzo[b]fluorenones via Ring Contraction by Benzil-Benzilic Acid Rearrangement of Benz[a]anthracene-5,6-diones

Abstract A regiospecific route to benzo[B]fluorenones is described. The synthesis is based upon a one-pot, regiospecific benzannulation of 1,4-dipolar synthons with naphthoquinone monoketal and ring contraction of the generated benz[A]anthracene-5,6-diones through benzil-benzilic acid rearrangement.
