Abstract

The olivomycins are representative antitumor antibiotics in the aureolic family of the compounds, which contains the tricyclic aglycon core, olivin. In this study, we established the efficient synthesis of the anthracenone core skeleton based on a cycloaddition reaction between the homophthalic anhydride and the chiral cyclohexenone derivatives, which is promoted by the combined use of molecular sieves, proton sponge, and a Lewis acid. The ...
