合成路线1
该中间体在本合成路线中的序号：(VIII)The condensation of chiral tetraline (I) with phthalic anhydride (II) by means of AlCl3 at 180 C gives the naphthacenedione (III), which is ketalized at the acetyl group with ethylene glycol and p-toluenesulfonic acid yielding the dioxolane (IV). The hydroxylation of (IV) with Br2 and AIBN in CCl4/CHCl3 affords the 4-demethoxy-7-epidaunomycinone (V), which is isomerized with TFA yielding 4-demethoxydaunomycinone (VI) . The condensation of (VI) with the acylated hexopyranosyl chloride (VII) by means of CF3SO3Ag of Br2Hg affords the trifluoroacetylated 4-demethoxydaunomycin (VIII), which is finally treated with NaOH in order to eliminate the trifluoroacetyl groups
