Isochrysophanol, isozyganein, ω-hydroxyisochrysophanol, and morindaparvin are naturallyoccurring substituted anthraquinones. We report the synthesis of these compounds as well as selected biological activities.

The characteristic features of vineomycinoneB2 (1) are the C-glycosyl bond to the olivose derivative, and the alkyl chain bearing a stereogenic center on the opposite side of the molecule. We report a triply convergent totalsynthesis of 1 which exploits methodology developed earlier in this group

A synthesis of substituted anthraquinones has been developed. Commercially available anthrarufin and 1,8-dihydroxyanthraquinone were converted to the corresponding (methoxymethoxy)anthracenes. Directed metalation followed by stannylation produced stable intermediates that were either alkylated, arylated, acylated, and/or C-glycosylated. The value of this new methodology was demonstrated by the triply convergent total synthesis of vineomycinone B2 methyl ester, a representative C-glycosylanthraquinone antibiotic.
