    • A method of preparing an anthracyclin such as epirubicin from a starting material comprising 13-dihydrodaunorubicine (13-daunorubicinol). The method comprises producing N-Trifluoroacetyl-13-daunorubicinol from 13-daunorubicinol by acylation. The N-Trifluoroacetyl-13-daunorubicinol is reacted with an aprotic solvent and an acylating agent to produce an intermediate sulfoxy salt which is treated with a strong base to produce 4'-keto-N-Trifluoroacetyldaunorubicin. The 4'-keto-N-Trifluoroacetyldaunorubicin is reacted with a reducing agent, such as borohydride of an alkaline metal, to produce N-Trifluoroacetyl-4'-epi-daunorubicin. The N-Trifluoroacetyl-4`-epi-daunorubicin is hydrolyzed in a basic solution to produce an intermediate compound. The intermediate compound is reacted with a halogenizing agent to produce a 14-Hal-derivative. The 14-Hal derivative is hydrolized in the presence of a formate of an alkaline metal to produce the desired final compound.
    • 从包含13-二氢阿柔比星(13-柔红霉素)的原料制备蒽环类似表柔比星的方法。 该方法包括通过酰化由13-柔红霉素生产N-三氟乙酰基-13-柔红霉素。 将N-三氟乙酰基-13-柔红霉素与非质子传递溶剂和酰化剂反应,生成中间体磺酰氧基盐,用强碱处理产生4'-酮 - 三氟乙酰基柔红霉素。 4'-酮-N-三氟乙酰基柔红霉素与还原剂如碱金属的硼氢化物反应,生成N-三氟乙酰基-4'-表柔比星。 将N-三氟乙酰基-4'-表柔比星在碱性溶液中水解以产生中间体化合物。 使中间体化合物与卤化剂反应生成14-Hal衍生物。 将14-Hal衍生物在碱金属甲酸盐存在下水解,得到所需的最终化合物。
