Ventinone A, a naturally occurring 1,4-dihydroxyanthraquinone has been synthesized in two steps from known compounds via a Hauser annulation. The same strategy, when applied to the synthesis of ventinone B, reveals that the proposed structure of ventinone

The phthalide sulfone 5 has been prepared from readily available ester 6 in four steps on multigram scales. This has been utilized in anionic [4 + 2] cycloaddition with a few cyclohexenones (12-14) to obtain anthraquinones (18-26) in good yields, compound
