合成路线1
该中间体在本合成路线中的序号：(III)Condensation of daunomycinone (I) with aminoglycal (II) in the presence of triphenylphosphine hydrobromide provided the protected hexopyranosyl daunomycinone (III). Deacetylation with K2CO3 in MeOH-CH2Cl2 gave alcohol (IV), and further hydrolysis of the trifluoroacetamide with NaOH yielded amine (V), which was isolated as the hydrochloride. Finally, condensation of two molecules of (V) with a,a'-dibromo-p-xylene (VI) in the presence of Na2CO3 in DMF-CH2Cl2 at room temperature, followed by precipitation of the dihydrochloride from MeOH-Et2O, provided the target compound.
