合成路线1
该中间体在本合成路线中的序号：(VI)Condensation of the magnesium iodide salt of 5-(benzyloxy)indole (I) with N-(benzyloxymethyl)-3,4-dibromomaleimide (II) provided the monoindolyl maleimide (III). Coupling of (III) with the benzyl-protected glucose (IV) via Mitsunobu reaction afforded the glycosylated indole (V). A second indolyl group was then introduced in (V) to give the bisindolylmaleimide (VI), which was oxidatively cyclized to the indolocarbazole (VII) using palladium bis(trifluoroacetate). Finally, hydrogenolysis of the benzyl protecting groups of (VII) over Pd/C furnished the title compound.
