合成路线1
该中间体在本合成路线中的序号：(III)The acylation of 3',4'-dideoxykanamycin B (dibekacin) (I) with N-benzyloxycarbonyloxysuccinimide (II) and zinc acetate in DMSO gives 3,2,6'-tri-N-benzyloxycarbonydibekacin (III), which is then treated with the N-hydroxysuccinimide ester of 2-hydroxy-4-aminobutyric acid (IV) and finally deprotected by hydrogenation with H2 over Pd/C in acidic water dioxane.

合成路线2
该中间体在本合成路线中的序号：(III)The acylation of 3,2,6'-tri-N-benzyloxycarbonydibekacin (III) with ethyl trifluoroacetate and K2CO3 gives 3,2',6'-tri-N-benzyloxycarbonyl-3''-trifluoroacetyldibekacin (VI), which is acylated again with (IV) yielding the protected habekacin (VII). Finally, this compound is deprotected by hydrolysis with ammonia in aqueous THF, followed by hydrogenolysis with H2 over Pd/C.
