摘要：

±)-7-Deoxy-4-demethoxydaunomycinone(±)-) was cleanly resolved by forming a mixture of the diastereomeric acetals (()- and (+)- or (+)- and ()- with the title -diol((+)- or ()-) to give optically pure (R)()-. The method for racemizing the undesired enantiomer((S)(+)-) was also explored. Optically pure (+)-4-demethoxydauno-mycinone ((+)-) was elaborated from (R)(-)- according to the reported reaction scheme.
