合成路线1
该中间体在本合成路线中的序号：(VII)The hydrolysis of DU-86 (I) with NaOMe gives tetracyclic compound (II), which is acylated with the 4-nitrophenyl cinnamate (III) and NaH yielding the adduct (IV). The opening of the cyclopropane ring of (IV) with HBr in acetonitrile affords the aromatic phenol (V), which is activated with 4-nitrophenyl chloroformate (VI) and TEA to provide the activated anhydride (VII). Finally, this compound is condensed with 4-methylpiperazine-1-amine (VIII), and treated with HBr to furnish the target dihydrobromide.
