  8-Hydroxyanthracyclinones from .epsilon.-rhodomycinone

  摘要：

  epsilon-Rhodomycinone was converted into 8,9-dehydro-zeta-rhodomycinone, which gave a cis diol with osmium tetroxide and a pair of epimeric epoxides with m-chloroperbenzoic acid. Acid-catalyzed opening of the epoxides gave the corresponding trans diols. In contrast, acid treatment of the trimethyl ethers of these epoxides gave predominantly a lactone and an eta-rhodomycinone derivative, with only small amounts of the diols. None of the new rhodomycinones were active against Bacillus subtilis, but 8,9-dehydro-zeta-rhodomycinone was active in the induction of lytic phage in Escherichia coli.
