摘要

Abstract The cheap, available dye-intermediate 1, 8-dihydroxyanthraquinone (2) is converted efficiently to a useful aklavinone precursor (3). A Mitsunobu alkylation-Claisen rearrangement sequence and an unprecedented vicarious aromatic substitution on an anthraquinone are employed as key steps.
