Regiospecific approaches to 6-deoxyanthracyclinones, which have resulted in the synthesis of the novel anthracyclines 4-demethoxy-6-deoxydaunorubicin (2) and 6-deoxycarminomycin (3), are reported. The construction of the aglycone 4 is based on the coupling of l,4-dimethoxy-2-lithionaphthalene (10) to 1 formyl-2-carbomethoxy-4-acetylcyclohexane thioketal (11). A new improved regioselective route, which
据报道,针对6-脱氧蒽环素的区域特异性方法已导致合成新型蒽环类4-脱甲氧基-6-脱氧柔红霉素(2)和6-脱氧卡那霉素(3)。糖苷配基4的构建基于1,4-二甲氧基-2-锂基萘(10)与1个甲酰基-2-羰基甲氧基-4-乙酰基环己烷硫缩酮(11)的偶联。一种新的改进的区域选择性途径,其允许6- deoxyanthracyclinones也轴承环取代基的制备d通过如图所示5,“一个基于所述耦合10A升的3,4,5-三甲氧基-3- lithionaphthalene(和图10b),以内酯28。
