  Stereo- and regioselective glycosylation of 4-deoxy-ε-rhodomycinone

  摘要：

  A method for the glycosylation of anthracyclines featuring benzoylated imidate donors has been developed and utilized in the synthesis of glycosylated 4-deoxy-epsilon-rhodomycinone derivatives. Due to its high efficiency, regioselectivity, stereoselectivity, and operational simplicity, the method should prove valuable to researchers working with glycosylation of tetracyclic compounds.
