Abstract

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.
