    摘要: Disclosed is a process for preparing the new antitumor glycosides: 4'-deoxy-3'-epi-daunorubicin and 4'-deoxy-3'-epi-doxorubicin starting from the known 3'-epi-4'-keto-N-trifluoroacetyl-daunorubicin.Reduction of the 4'-keto group with sodium borohydride to the corresponding 4'-hydroxy group, reacting the so obtained intermediate with trifluoromethanesulphonic anhydride followed by treatment with n-tetrabutylammonium iodide, dehalogenated reductively, by treatment with tributyl tin hydride to 4'-deoxy-3'-epi-N-trifluoroacetyl-daunorubicin.A mild alkaline hydrolysis removes the N-protecting group to give 4'-deoxy-3'-epi-daunorubicin which is successively transformed, via its 14-bromo derivative, in its doxorubicin analogue.
